+title: Qubes builder v2
+---
+
+This is a brief introduction to using Qubes Builder v2 to work with Qubes OS
+sources. It will walk you through installing and configuring Builder v2, and
+using it to fetch and build Qubes OS packages.
+
+For details and customization, use [Qubes OS v2 builder documentation](https://github.com/QubesOS/qubes-builderv2/).
+
+# Overview
+
+In the second generation of Qubes OS builder, container or disposable qube
+isolation is used to perform every stage of the build and release process.
+From fetching sources to building, everything is executed inside an isolated
+*cage* (either a disposable or a container) using an *executor*. For every
+command that needs to perform an action on sources, like cloning and
+verifying Git repos, rendering a SPEC file, generating SRPM or Debian
+source packages, a new cage is used. Only the signing, publishing, and
+uploading stages are executed locally outside a cage.
+
+
+# Setup
+
+This is a simple setup using a docker executor. This is a good default choice;
+if you don't know which executor to use, use docker.
+
+1. First, decide what qube you are going to use when working with Qubes
+   Builder v2. It can be an AppVM or a Standalone qube, with some steps
+   different between the two.
+
+2. Installing dependencies
+
+   If you want to use an app qube for developing, install dependencies in the template.
+   If you are using a standalone, install them in the qube itself.
+    Dependencies are specified in `dependencies-*.
+   txt` files in the main builder directory, and you can install them easily
+   in the following ways:
+   1. for Fedora, use:
+    ```shell
+    $ sudo dnf install $(cat dependencies-fedora.txt)
+    $ test -f /usr/share/qubes/marker-vm && sudo dnf install qubes-gpg-split
+   ```
+   2. for Debian (note: some Debian packages require Debian version 13 or
+      later), use:
+    ```shell
+    $ sudo apt install $(cat dependencies-debian.txt)
+    $ test -f /usr/share/qubes/marker-vm && sudo apt install qubes-gpg-split
+   ```
+
+    If you have installed dependencies in the template, close it, and
+    (re)start the development qube.
+
+3. Clone the qubes-builder v2 repository into a location of your choice:
+    ```shell
+    git clone https://github.com/QubesOS/qubes-builderv2
+    cd qubes-builderv2/
+    ```
+
+4. If you haven't previously used docker in the current qube, you need to set up
+   some permissions. In particular, the user has to be added to the `docker`
+   group:
+    ```shell
+   $ sudo usermod -aG docker user
+    ```
+    Next, **restart the qube**.
+
+5. Finally, you need to generate a docker image:
+    ```shell
+   $ tools/generate-container-image.sh docker
+    ```
+
+   In an app qube, as `/var/lib/docker` is not persistent by default, you also
+   need to use [bind-dirs](/doc/bind-dirs/) to avoid repeating this step after reboot, adding
+   the following to the `/rw/config/qubes-bind-dirs.d/docker.conf` file in
+   this qube:
+
+   ```
+   binds+=( '/var/lib/docker' )
+   ```
+
+# Configuration
+
+To use Qubes OS Builder v2, you need to have a `builder.yml` configuration file.
+You can use one of the sample files from the `example-configs/` directory; for a
+more readable `builder.yml`, you can also include one of the files from that
+directory in your `builder.yml`. An example `builder.yml` is:
+
+```yaml
+# include configuration relevant for the current release
+include:
+- example-configs/qubes-os-r4.2.yml
+
+# which repository to use to fetch sources
+use-qubes-repo:
+  version: 4.2
+  testing: true
+
+# each package built will have local build number appended to package release
+# number. It makes it easier to update in testing environment
+increment-devel-versions: true
+
+# reduce output
+debug: false
+
+# this can be set to true if you do not want sources to be automatically
+# fetched from git
+skip-git-fetch: false
+
+# executor configuration
+executor:
+  type: docker
+  options:
+    image: "qubes-builder-fedora:latest"
+
+```
+
+
+# Using Builder v2
+
+To fetch sources - in this example, for the `core-admin-client` package, you
+can use the following command:
+
+```shell
+$ ./qb -c core-admin-client package fetch
+```
+
+This will fetch the sources for the listed package and place them in
+`artifacts/sources` directory.
+
+To build a package (from sources in the `artifacts/sources` directory), use:
+
+```shell
+$ ./qb -c core-admin-client package fetch prep build
+```
+
+or, if you want to build for a specific target (`host-fc37` is a `dom0`
+using Fedora 37, `vm-fc40` would be a qube using Fedora 40 etc.), use:
+
+```shell
+$ ./qb -c core-admin-client -d host-fc37 package fetch prep build
+```
+
+If you want to fetch the entire Qubes OS source use the following:
+
+```shell
+$ ./qb package fetch
+```
+
+**caution**: some repositories might have additional requirements. You can
+disable repositories that are not needed in the `example-configs/*.yml`
+file you are using by commenting them out. In particular, `python-fido2`,
+`lvm` and `windows`-related repositories have special requirements.

+## Device Serialization
+
+Both device and assignment serialization is ASCII-encoded and contains 
+space-separated key-value pairs. The format includes an `=` between the key 
+and value, and the value is always enclosed in single quotes (`'`). 
+Values may contain spaces or even single quotes, which are escaped with a backslash. 
+If a value is not set (`None`), it is represented as `'unknown'`. 
+For boolean values, `True` is represented as `'yes'`, and `False` as `'no'`. 
+The order of key-value pairs is irrelevant. Keys starting with `_` 
+are considered extra properties and are saved in `data` or `options` 
+for device or assignment respectively.
+
+Information about the serialization format of specific properties can be found below.
+
+Format:
+```
+<ident> <property_1>='<value_1>' <property_2>='<value_2>' <property_3>='<value_3>'...
+```
+
+Detailed serialization format for a device:
+
+- `ident='<ident>'`
+- `backend_domain='<backend_domain.name>'`
+- `devclass='<devclass>'`
+- `vendor='<vendor>'`
+- `product='<product>'`
+- `manufacturer='<manufacturer>'`
+- `name='<name>'`
+- `serial='<serial>'`
+- `self_identity='<self_identity>'`
+- `interfaces='<interface1><interface2>...'`
+    Each device interface is represented with a 7-character length. Each device has at least one interface. Since the length of the interface representation is known, they are serialized as a single string with each interface representation concatenated one after another. The order is irrelevant.
+- `parent_ident='<parent.ident>' parent_devclass='<parent.devclass>'`
+- `attachment='<attachment.name>'`
+- `_<key1>='<value1>' _<key2>='<value2>' ...` (extra parameters)
+
+Detailed serialization format for an assignment:
+
+- `ident='<ident>'`
+- `backend_domain='<backend_domain.name>'`
+- `devclass='<devclass>'`
+- `frontend_domain='<frontend_domain.name>'`
+- `required='<yes/no>'` (default 'no')
+- `attach_automatically='<yes/no>'` (default 'no')
+- `_<key1>='<str(value1)>' _<key2>='<str(value2)>' ...` (options)
+
+Example device serialization:
+
+```
+1-1.1.1 manufacturer='unknown' self_identity='0000:0000::?******' serial='unknown' ident='1-1.1.1' product='Qubes' vendor='ITL' name='Some untrusted garbage' devclass='bus' backend_domain='vm' interfaces=' ******u03**01' _additional_info='' _date='06.12.23' parent_ident='1-1.1' parent_devclass='None'

+Besides enabling IPv6 forwarding, the standard Qubes firewall can be used to limit what network resources are available to each qube. Currently only the `qvm-firewall` command supports adding IPv6 rules, the GUI firewall editor will have this ability later.
+
+**Note:** Setting or unsetting the `ipv6` feature only affects qubes-configured networking. It does not affect e.g. external interfaces. If you want to restrict IPv6 on these interfaces change the settings in Network Manager. Alternatively, disable IPv6 support using methods appropriate to the underlying template.
 
 ### Limitations
 
 Currently only IPv4 DNS servers are configured, regardless of `ipv6` feature state. It is done this way to avoid reconfiguring all connected qubes whenever IPv6 DNS becomes available or not. Configuring qubes to always use IPv6 DNS and only fallback to IPv4 may result in relatively long timeouts and poor usability.
 But note that DNS using IPv4 does not prevent to return IPv6 addresses. In practice this is only a problem for IPv6-only networks.

 standalones to be HVMs and for HVMs to be standalones. Hence, this page covers
 both topics.
 
+## Understanding Virtualization Modes
+
+PVH has both better performance and better security than either PV or HVM:
+
+PVH has less attack surface than PV, as it relies on Second Level Address Translation (SLAT) hardware. Guests modify their own page tables natively, without hypervisor involvement. Xen does not need to perform complex checks to ensure that a guest cannot obtain write access to its own page tables, as is necessary for PV. Flaws in these checks have been a source of no fewer than four guest ⇒ host escapes: XSA-148, XSA-182, XSA-212, and XSA-213.
+
+PVH also has less attack surface than HVM, as it does not require QEMU to provide device emulation services. While QEMU is confined in a stubdomain, and again in a seccomp based sandbox, the stubdomain has significant attack surface against the hypervisor. Not only does it have the full attack surface of a PV domain, it also has access to additional hypercalls that allow it to control the guest it is providing emulation services for. XSA-109 was a vulnerability in one of these hypercalls.
+
+PVH has better performance than HVM, as the stubdomain iin HVM consumes resources (both memory and a small amount of CPU). There is little difference in the I/O path at runtime, as both PVH and HVM guests usually use paravirtualized I/O protocols.
+
+Surprisingly, PVH often has better performance than PV. This is because PVH does not require hypercalls for page table updates, which are expensive. SLAT does raise the cost of TLB misses, but this is somewhat mitigated by a second-level TLB in recent hardware.

 Periodic upgrades are also important for templates. For example, you might be using a [Fedora template](/doc/templates/fedora/). The [Fedora Project](https://getfedora.org/) is independent of the Qubes OS Project. They set their own [schedule](https://fedoraproject.org/wiki/Fedora_Release_Life_Cycle#Maintenance_Schedule) for when each Fedora release reaches EOL. You can always find out when an OS reaches EOL from the upstream project that maintains it. We also pass along any EOL notices we receive for official template OSes as a convenience to Qubes users (see the [supported template releases](/doc/supported-releases/#templates)).
 
 The one exception to all this is the specific release used for dom0 (not to be confused with Qubes OS as a whole), which [doesn't have to be upgraded](/doc/supported-releases/#note-on-dom0-and-eol).
+
+## Microcode Updates
+
+x86\_64 CPUs contain special low-level software called **microcode**, which
+is used to implement certain instructions and runs on various processors that
+are outside of Qubes OS's control.  Most microcode is in an on-CPU ROM, but
+CPU vendors provide patches that modify small parts of this microcode.  These
+patches can be loaded from the BIOS or by the OS.
+
+The fixes for some QSBs require a microcode update to work. Furthermore,
+microcode updates will sometimes fix vulnerabilities "silently". This means
+that the vulnerability impacts the security of Qubes OS, but the Qubes OS
+Security Team is not informed that a vulnerability exists, so no QSB is ever
+issued. Therefore, it is critical to update microcode.
+
+Intel provides microcode updates for all of their CPUs in a public Git
+repository, and allows OS vendors (such as Qubes OS) to distribute the updates
+free of charge.  AMD, however, only provides microcode for server CPUs.
+AMD client CPUs can only receive microcode updates via a system firmware
+update.  Worse, there is often a significant delay between when a vulnerability
+becomes public and when firmware that includes updated microcode is available
+to Qubes OS users.  This is why Qubes OS recommends Intel CPUs instead of
+AMD CPUs.
+
+## Firmware updates
+
+Modern computers have many processors other than those that run Qubes OS.
+Furthermore, the main processor cores also run firmware, which is used to
+boot the system and often provides some services at runtime.  Both kinds
+of firmware can have bugs and vulnerabilities, so it is critical to keep
+them updated.
+
+Some firmware is loaded by the OS at runtime.
+Such firmware is provided by the `linux-firmware` package and can be updated the usual way.
+Other devices have persistent firmware that must be updated manually.
+
+Qubes OS supports updating system firmware in three different ways.
+Which one to use depends on the device whose firmware is being updated.
+
+- If a device is attached to a domU, it should be updated using **fwupd**.
+  fwupd is included in both Debian and Fedora repositories.
+  It requires Internet access to use, but you can use the updates proxy if you
+  need to update firmware from an offline VM.  You can use either the
+  command-line `fwupdmgr` tool or any of the graphical interfaces to fwupd.
+
+- If a device is attached to dom0, use the `qubes-fwupdmgr` command-line tool.
+  This tool uses fwupd internally, but it fetches firmware and metadata over
+  qrexec from the dom0 UpdateVM, rather than fetching them from the Internet.
+  Unfortunately, their is no graphical interface for this tool yet.
+
+- System76 systems use a special update tool which is simpler than fwupd.
+  Support for this tool is currently in progress.  Once it is finished,
+  users will be able to use the **system76-firmware-cli** command-line
+  tool to update the firmware.

+Using Qube Manager you can quickly determine the controllers on your system and their BDF addresses, but not which controller a particular device is attached to.
+
+Open the Qube Manager, then right click on one of the qubes and open the settings. Go to the tab "Devices".
+Here you should see your available devices along with their BDF addresses. Look for the lines containing "USB controller".
+They should look something like: `01:00.0 USB controller: Name of manufacturer`
+
+The first part is the BDF address, in this example: `01:00.0`
+
+If, for example, you have 2 USB controllers in your system because you added one you should see 2 such lines and you can probably guess which controller is the one on the mainboard and which one you added. For example, if you have a mainboard with an Intel chipset, it is possible that all of the mainboard devices show as "Intel Corporation", while the added controller shows another manufacturer's name.
+
+Now you should be able to tell which is the BDF address of the mainboard USB controller or the added USB controller.

-### Setting up the GPG backend domain
+In dom0 enable the `split-gpg2-client` service in the client domain, for example via the command-line:
 
-First, create a dedicated app qube for storing your keys (we will be calling it the GPG backend domain).
+```shell
-It is recommended that this domain be network disconnected (set its netvm to `none`) and only used for this one purpose.
+dom0$ qvm-service <SPLIT_GPG2_CLIENT_DOMAIN_NAME> split-gpg2-client on
-In later examples this app qube is named `work-gpg`, but of course it might have any other name.
-
-Make sure that gpg is installed there.
-At this stage you can add the private keys you want to store there, or you can now set up Split GPG and add the keys later.
-To check which private keys are in your GPG keyring, use:
-
-```shell_session
-[user@work-gpg ~]$ gpg -K
-/home/user/.gnupg/secring.gpg
------------------------------
-sec   4096R/3F48CB21 2012-11-15

-ssb   4096R/30498E2A 2012-11-15
-(...)
 ```
 
-This is pretty much all that is required.
+To verify if this was done correctly:
-However, you might want to modify the default timeout: this tells the backend for how long the user's approval for key access should be valid.
-(The default is 5 minutes.) You can change this via the `QUBES_GPG_AUTOACCEPT` environment variable.
-You can override it e.g. in `~/.profile`:
 
-```shell_session

-### Configuring the client apps to use Split GPG backend
-
-Normally it should be enough to set the `QUBES_GPG_DOMAIN` to the GPG backend domain name and use `qubes-gpg-client` in place of `gpg`, e.g.:
-
-```shell_session
-[user@work-email ~]$ export QUBES_GPG_DOMAIN=work-gpg
-[user@work-email ~]$ gpg -K
-[user@work-email ~]$ qubes-gpg-client -K

-(...)
-
-[user@work-email ~]$ qubes-gpg-client secret_message.txt.asc

-Note that running normal `gpg -K` in the demo above shows no private keys stored in this app qube.
+Restart the client domain.
 
-A note on `gpg` and `gpg2`:
+Export the **public** part of your keys and import them in the client domain.
-
+Also import/set proper "ownertrust" values.
-Throughout this guide, we refer to `gpg`, but note that Split GPG uses `gpg2` under the hood for compatibility with programs like Enigmail (which now supports only `gpg2`).
+For example:
-If you encounter trouble while trying to set up Split GPG, make sure you're using `gpg2` for your configuration and testing, since keyring data may differ between the two installations.
-
-### Advanced Configuration
-
-The `qubes-gpg-client-wrapper` script sets the `QUBES_GPG_DOMAIN` variable automatically based on the content of the file `/rw/config/gpg-split-domain`, which should be set to the name of the GPG backend VM. This file survives the app qube reboot, of course.
-
-```shell_session
-[user@work-email ~]$ sudo bash
-[root@work-email ~]$ echo "work-gpg" > /rw/config/gpg-split-domain
-```
-
-Split GPG's default qrexec policy requires the user to enter the name of the app qube containing GPG keys on each invocation. To improve usability for applications like Thunderbird with Enigmail, in `dom0` place the following line at the top of the file `/etc/qubes-rpc/policy/qubes.Gpg`:
 
 ```
-work-email  work-gpg  allow
+gpg-server-vm$ gpg --export > public-keys-export
+gpg-server-vm$ gpg --export-ownertrust > ownertrust-export
+gpg-server-vm$ qvm-copy public-keys-export ownertrust-export
+
+gpg-client-vm$ gpg --import ~/QubesIncoming/gpg-server-vm/public-keys-export
+gpg-client-vm$ gpg --import-ownertrust ~/QubesIncoming/gpg-server-vm/ownertrust-export
 ```
 
-where `work-email` is the Thunderbird + Enigmail app qube and `work-gpg` contains your GPG keys.
+This should be enough to have it running:
-
-You may also edit the qrexec policy file for Split GPG in order to tell Qubes your default gpg vm (qrexec prompts will appear with the gpg vm preselected as the target, instead of the user needing to type a name in manually). To do this, append `default_target=<vmname>` to `ask` in `/etc/qubes-rpc/policy/qubes.Gpg`. For the examples given on this page:
-
 ```
-@anyvm  @anyvm  ask default_target=work-gpg
+gpg-client-vm$ gpg -K
-```
-
-Note that, because this makes it easier to accept Split GPG's qrexec authorization prompts, it may decrease security if the user is not careful in reviewing presented prompts. This may also be inadvisable if there are multiple app qubes with Split GPG set up.

-Starting with version 78, Thunderbird has a built-in PGP feature and no longer requires the Enigmail extension. For users coming from the Enigmail extension, the built-in functionality is more limited currently, including that **public keys must live in your `work-email` qube with Thunderbird rather than your offline `work-gpg` qube**.
-
-In `work-email`, use the Thunderbird config editor (found at the bottom of preferences/options), and search for `mail.openpgp.allow_external_gnupg`. Switch the value to true. Still in config editor, search for `mail.openpgp.alternative_gpg_path`. Set its value to `/usr/bin/qubes-gpg-client-wrapper`. Restart Thunderbird after this change.

-The key ID reference you would need here is `777402E6D301615C`. Now paste or type the ID of the secret key that you would like to use. Be careful to enter it correctly, because your input isn't verified. Confirm to save this key ID. Now you can select the key ID to use.
+split-gpg2 only knows a hash of the data being signed.
+Therefore, it cannot differentiate between e.g. signatures of a piece of data or signatures of another key.
+This means that a client can use split-gpg2 to sign other keys, which split-gpg1 did not allow.
 
-[![tb78-6.png](/attachment/doc/tb78-6.png)](/attachment/doc/tb78-6.png)
+To prevent this, split-gpg2 creates a new GnuPG home directory and imports the secret subkeys (**not** the primary key!) to it.
-[![tb78-7.png](/attachment/doc/tb78-7.png)](/attachment/doc/tb78-7.png)
+Clients will be able to use the secret parts of the subkeys, but not of the primary key.
+If your primary key is able to sign data and certify other keys, and your only subkey can only perform encryption, this means that all signing will fail.
+To make signing work again, generate a subkey that is capable of signing but **not** certification.
+split-gpg2 does not generate this key for you, so you need to generate it yourself.
+If you want to generate a key in software, use the `addkey` command of `gpg2 --edit-key`.
+If you want to generate a key on a smartcard or other hardware token, use `addcardkey` instead.
 
-This key ID will be used to digitally sign or send an encrypted message with your account. For this to work, Thunderbird needs a copy of your public key. At this time, Thunderbird doesn't fetch the public key from `/usr/bin/qubes-gpg-client-wrapper`, you must manually import it. Export the key as follow (assuming the key ID would be `777402E6D301615C`):
+## Advanced usage
 
-[![tb78-8.png](/attachment/doc/tb78-8.png)](/attachment/doc/tb78-8.png)

+See the comments in the example (config and the source code)[https://github.com/QubesOS/qubes-app-linux-split-gpg2/blob/main/qubes-split-gpg2.conf.example].
 
-Use Thunderbird's Tools menu to open *OpenPGP Key Management*. In that window, use the File menu to access the *Import Public Key(s) From File* command. Open the file with your public key. After the import was successful, right click on the imported key in the list and select *Key Properties*. You must mark your own key as *Yes, I've verified in person this key has the correct fingerprint*.
+Similar to a smartcard, split-gpg2 only tries to protect the private key.
+For advanced usages, consider if a specialized RPC service would be better.
+It could do things like checking what data is singed, detailed logging, exposing the encrypted content only to a VM without network, etc.
 
-Once this is done, you should be able to send an encrypted and signed email by selecting *Require Encryption* or *Digitally Sign This Message* in the compose menu *Options* or *Security* toolbar button. You can try it by sending an email to yourself.
+Using split-gpg2 as the "backend" for split-gpg1 is known to work.

-For more details about using smart cards/Split GPG with Thunderbird PGP feature, please see [Thunderbird:OpenPGP:Smartcards](https://wiki.mozilla.org/Thunderbird:OpenPGP:Smartcards) from which the above documentation is inspired.
+By setting `allow_keygen = yes` in `qubes-split-gpg2.conf` you can allow the client to generate new keys.
+Normal usage should not need this.
 
-### Older Thunderbird versions
+**Warning**: This feature is new and not much tested.
+Therefore it's not security supported!
 
-For Thunderbird versions below 78, the traditional Enigmail + Split GPG setup is required.
+## Copyright
-It is recommended to set up and use `/usr/bin/qubes-gpg-client-wrapper`, as discussed above, in Thunderbird through the Enigmail addon.
 
-**Warning:** Before adding any account, configuring Enigmail with `/usr/bin/qubes-gpg-client-wrapper` is **required**. By default, Enigmail will generate a default GPG key in `work-email` associated with the newly created Thunderbird account. Generally, it corresponds to the email used in `work-gpg` associated to your private key. In consequence, a new, separate private key will be stored in `work-email` but it _does not_ correspond to your private key in `work-gpg`. Comparing the `fingerprint` or `expiration date` will show that they are not the same private key. In order to prevent Enigmail using this default generated local key in `work-email`, you can safely remove it.

-Keybase, a security focused messaging and file-sharing app with GPG integration, can be configured to use Split GPG.
+51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
-
-The Keybase service does not preserve/pass the `QUBES_GPG_DOMAIN` environment variable through to underlying GPG processes, so it **must** be configured to use `/usr/bin/qubes-gpg-client-wrapper` (as discussed above) rather than `/usr/bin/qubes-gpg-client`.
-
-The following command will configure Keybase to use `/usr/bin/qubes-gpg-client-wrapper` instead of its built-in GPG client:
-
-```
-$ keybase config set gpg.command /usr/bin/qubes-gpg-client-wrapper
-```
-
-Now that Keybase is configured to use `qubes-gpg-client-wrapper`, you will be able to use `keybase pgp select` to choose a GPG key from your backend GPG app qube and link that key to your Keybase identity.
-
-## Using Git with Split GPG
-
-Git can be configured to utilize Split GPG, something useful if you would like to contribute to the Qubes OS Project as every commit is required to be signed.
-The most basic `~/.gitconfig` file enabling Split GPG looks something like this.
-
-```
-[user]
-	name = <YOUR_NAME>
-	email = <YOUR_EMAIL_ADDRESS>
-	signingKey = <YOUR_KEY_ID>
-
-[gpg]
-	program = qubes-gpg-client-wrapper
-```
-
-Your key id is the public id of your signing key, which can be found by running `qubes-gpg-client --list-keys`.
-In this instance, the key id is E142F75A6B1B610E0E8F874FB45589245791CACB.
-
-```shell_session
-[user@work-email ~]$ qubes-gpg-client --list-keys
-/home/user/.gnupg/pubring.kbx
------------------------------
-pub   ed25519 2022-08-16 [C]

-sub   cv25519 2022-08-16 [E]
-sub   ed25519 2022-08-16 [A]
-```
-
-To sign commits, you now add the "-S" flag to your commit command, which should prompt for Split GPG usage.
-If you would like to automatically sign all commits, you can add the following snippet to `~/.gitconfig`.
-
-```
-[commit]
-	gpgSign = true
-```
-
-Lastly, if you would like to add aliases to sign and verify tags using the conventions the Qubes OS Project recommends, refer to the [code signing documentation](/doc/code-signing/#using-pgp-with-git).
-
-## Importing public keys
-
-Use `qubes-gpg-import-key` in the client app qube to import the key into the GPG backend VM.
-
-```shell_session
-[user@work-email ~]$ export QUBES_GPG_DOMAIN=work-gpg
-[user@work-email ~]$ qubes-gpg-import-key ~/Downloads/marmarek.asc
-```
-
-A safe, unspoofable user consent dialog box is displayed.
-
-[![r2-split-gpg-5.png](/attachment/doc/r2-split-gpg-5.png)](/attachment/doc/r2-split-gpg-5.png)
-
-Selecting "Yes to All" will add a line in the corresponding [RPC Policy](/doc/rpc-policy/) file.
-
-## Advanced: Using Split GPG with Subkeys
-
-Users with particularly high security requirements may wish to use Split GPG with [subkeys](https://wiki.debian.org/Subkeys).
-However, this setup comes at a significant cost: It will be impossible to sign other people's keys with the master secret key without breaking this security model.
-Nonetheless, if signing others' keys is not required, then Split GPG with subkeys offers unparalleled security for one's master secret key.
-
-### Setup Description
-
-In this example, the following keys are stored in the following locations (see below for definitions of these terms):
-
-| PGP Key(s) | VM Name      |
-| ---------- | ------------ |
-| `sec`      | `vault`      |
-| `ssb`      | `work-gpg`   |
-| `pub`      | `work-email` |
-
-* `sec` (master secret key)
-
-   Depending on your needs, you may wish to create this as a **certify-only (C)** key, i.e., a key which is capable only of signing (a.k.a., "certifying") other keys.
-   This key may be created *without* an expiration date.
-   This is for two reasons.
-   First, the master secret key is never to leave the `vault` VM, so it is extremely unlikely ever to be obtained by an adversary (see below).
-   Second, an adversary who *does* manage to obtain the master secret key either possesses the passphrase to unlock the key (if one is used) or does not.
-   An adversary who *does* possess the passphrase can simply use it to legally extend the expiration date of the key (or remove it entirely).
-   An adversary who does *not* possess the passphrase cannot use the key at all.
-   In either case, an expiration date provides no additional benefit.
-
-   By the same token, however, having a passphrase on the key is of little value.
-   An adversary who is capable of stealing the key from your `vault` would almost certainly also be capable of stealing the passphrase as you enter it.
-   An adversary who obtains the passphrase can then use it in order to change or remove the passphrase from the key.
-   Therefore, using a passphrase at all should be considered optional.
-   It is, however, recommended that a **revocation certificate** be created and safely stored in multiple locations so that the master keypair can be revoked in the (exceedingly unlikely) event that it is ever compromised.
-
-* `ssb` (secret subkey)
-
-   Depending on your needs, you may wish to create two different subkeys: one for **signing (S)** and one for **encryption (E)**.
-   You may also wish to give these subkeys reasonable expiration dates (e.g., one year).
-   Once these keys expire, it is up to you whether to *renew* these keys by extending the expiration dates or to create *new* subkeys when the existing set expires.
-
-   On the one hand, an adversary who obtains any existing encryption subkey (for example) will be able to use it in order to decrypt all emails (for example) which were encrypted to that subkey.
-   If the same subkey were to continue to be used--and its expiration date continually extended--only that one key would need to be stolen (e.g., as a result of the `work-gpg` VM being compromised; see below) in order to decrypt *all* of the user's emails.
-   If, on the other hand, each encryption subkey is used for at most approximately one year, then an adversary who obtains the secret subkey will be capable of decrypting at most approximately one year's worth of emails.
-
-   On the other hand, creating a new signing subkey each year without renewing (i.e., extending the expiration dates of) existing signing subkeys would mean that all of your old signatures would eventually read as "EXPIRED" whenever someone attempts to verify them.
-   This can be problematic, since there is no consensus on how expired signatures should be handled.
-   Generally, digital signatures are intended to last forever, so this is a strong reason against regularly retiring one's signing subkeys.
-
-* `pub` (public key)
-
-   This is the complement of the master secret key.
-   It can be uploaded to keyservers (or otherwise publicly distributed) and may be signed by others.
-
-* `vault`
-
-   This is a network-isolated VM.
-   The initial master keypair and subkeys are generated in this VM.
-   The master secret key *never* leaves this VM under *any* circumstances.
-   No files or text is *ever* [copied](/doc/how-to-copy-and-move-files/#security) or [pasted](/doc/how-to-copy-and-paste-text/#security) into this VM under *any* circumstances.
-
-* `work-gpg`
-
-   This is a network-isolated VM.
-   This VM is used *only* as the GPG backend for `work-email`.
-   The secret subkeys (but *not* the master secret key) are [copied](/doc/how-to-copy-and-move-files/#security) from the `vault` VM to this VM.
-   Files from less trusted VMs are *never* [copied](/doc/how-to-copy-and-move-files/#security) into this VM under *any* circumstances.
-
-* `work-email`
-
-   This VM has access to the mail server.
-   It accesses the `work-gpg` VM via the Split GPG protocol.
-   The public key may be stored in this VM so that it can be attached to emails and for other such purposes.
-
-### Security Benefits
-
-In the standard Split GPG setup, there are at least two ways in which the `work-gpg` VM might be compromised.
-First, an attacker who is capable of exploiting a hypothetical bug in `work-email`'s [MUA](https://en.wikipedia.org/wiki/Mail_user_agent) could gain control of the `work-email` VM and send a malformed request which exploits a hypothetical bug in the GPG backend (running in the `work-gpg` VM), giving the attacker control of the `work-gpg` VM.
-Second, a malicious public key file which is imported into the `work-gpg` VM might exploit a hypothetical bug in the GPG backend which is running there, again giving the attacker control of the `work-gpg` VM.
-In either case, such an attacker might then be able to leak both the master secret key and its passphrase (if any is used, it would regularly be input in the work-gpg VM and therefore easily obtained by an attacker who controls this VM) back to the `work-email` VM or to another VM (e.g., the `netvm`, which is always untrusted by default) via the Split GPG protocol or other [covert channels](/doc/data-leaks/).
-Once the master secret key is in the `work-email` VM, the attacker could simply email it to himself (or to the world).
-
-In the alternative setup described in this section (i.e., the subkey setup), even an attacker who manages to gain access to the `work-gpg` VM will not be able to obtain the user's master secret key since it is simply not there.
-Rather, the master secret key remains in the `vault` VM, which is extremely unlikely to be compromised, since nothing is ever copied or transferred into it.
-[^a-note] The attacker might nonetheless be able to leak the secret subkeys from the `work-gpg` VM in the manner described above, but even if this is successful, the secure master secret key can simply be used to revoke the compromised subkeys and to issue new subkeys in their place.
-(This is significantly less devastating than having to create a new *master* keypair.)
-
-[^a-note]: In order to gain access to the `vault` VM, the attacker would require the use of, e.g., a general Xen VM escape exploit or a [signed, compromised package which is already installed in the template](/doc/templates/#trusting-your-templates) upon which the `vault` VM is based.

-(Note: Although the tutorials below were not written with Qubes Split GPG in mind, they can be adapted with a few commonsense adjustments.
-As always, exercise caution and use your good judgment.)

-
-## Current limitations
-
-* Current implementation requires importing of public keys to the vault domain.
-  This opens up an avenue to attack the gpg running in the backend domain via a hypothetical bug in public key importing code.
-  See ticket [#474](https://github.com/QubesOS/qubes-issues/issues/474) for more details and plans how to get around this problem, as well as the section on [using Split GPG with subkeys](#advanced-using-split-gpg-with-subkeys).
-
-* It doesn't solve the problem of allowing the user to know what is to be signed before the operation gets approved.
-  Perhaps the GPG backend domain could start a disposable and have the to-be-signed document displayed there? To Be Determined.
-
-* The Split GPG client will fail to sign or encrypt if the private key in the GnuPG backend is protected by a passphrase.
-  It will give an `Inappropriate ioctl for device` error.
-  Do not set passphrases for the private keys in the GPG backend domain.
-  Doing so won't provide any extra security anyway, as explained in the introduction and in [using Split GPG with subkeys](#advanced-using-split-gpg-with-subkeys).
-  If you are generating a new key pair, or if you have a private key that already has a passphrase, you can use `gpg2 --edit-key <key_id>` then `passwd` to set an empty passphrase.
-  Note that `pinentry` might show an error when you try to set an empty passphrase, but it will still make the change.
-  (See [this StackExchange answer](https://unix.stackexchange.com/a/379373) for more information.)
-  Note: The error shows only if you **do not** have graphical pinentry installed.

 ## Windows as a template
 
-As described above Windows 7, 8.1, 10 and 11 can be installed as TemplateVM. To have the user data stored in AppVMs depending on this template, the option `Move User Profiles` has to be selected on installation of Qubes Windows Tools. For Windows 7, before installing QWT, the private disk `D:` has to be renamed to `Q:`, see the QWT installation documentation in [Qubes Windows Tools](/doc/templates/windows/qubes-windows-tools-4-1).
+As described above Windows 7, 8.1, 10, and 11 can be installed as TemplateVM. To have the user data stored in AppVMs depending on this template, the user data have to be stored on a private disk named `Q:`. If there is already a disk for user data, possibly called `D:`, it has to be renamed to `Q:`. Otherwise, this disk has to be created via the Windows `diskpart` utility, or the Disk Management administrative function by formatting the qube's private volume and associating the letter `Q:` with it. The volume name is of no importance.
+
+Moving the user data is not directly possible under Windows, because the directory `C:\Users` is permanently open and thus locked. Qubes Windows Tools provides a function to move these data on Windows reboot when the directory is not yet locked. To use this function, a working version of QWT has to be used (see the documentation on QWT installation). For Qubes R4.2, this is currently the version 4.1.69. There are two possibilities to move the user data to this volume `Q:`.
+
+- If Qubes Windows Tools is installed, the option `Move User Profiles` has to be selected on the installation. In this case, the user files are moved to the new disk during the reboot at the end of the installation.
+
+- This can also be accomplished without QWT installation, avoiding the installation of the Xen PV drivers, if the risk of a compromised version of these drivers according to QSB-091 is considered too severe. In this case, the file `relocate_dir.exe` has to be extracted from the QWT installer kit `qubes-tools-x64.msi`, which will be shown as the content of the CDROM made available by starting the Windows qube with the additional option `--install-windows-tools` (see the QWT installation documentation). The installer kit is a specially formatted archive, from which the file `relocate_dir.exe` can be extracted using a utility like 7-Zip. The file has then to be copied to `%windir%\system32`, i.e. usually `C:\Windows\system32`. Furthermore, locate the registry key `HKLM\SYSTEM\CurrentControlSet\Control\Session Manager`, and add the text `relocate_dir.exe C:\Users Q:\Users` as a new line to the `REG_MULTI_SZ` value `\BootExecute` in this key. On rebooting the Windows qube, the user files will be moved to the disk `Q:`, and the additional registry entry will be removed, such that this action occurs only once.
+
+If the user data have been moved to `Q:`, be sure not to user the option `Move User Profeiles`on subsequent installations of Qubes Windows tools.

+## `notify-send` induced failure
+[Some VPN guides](https://forum.qubes-os.org/t/configuring-a-proxyvm-vpn-gateway/19061) use complex scripts that include a call to `notify-send`, yet some images may not contain this tool or may not have it working properly.
+For instance calling `notify-send` on a `fedora-36` template VM gives:
+```
+Failed to execute child process “dbus-launch” (No such file or directory)
+```
+
+To check this tool is working properly run:
+```bash
+sudo notify-send "$(hostname): Test notify-send OK" --icon=network-idle
+```
+You should see the `info` message appear on the top of your screen.
+If that is the case then `notify-send` is not the issue.
+If it is not, and you have an error of some sort you can:
+1. Remove all calls to `notify-send` from scripts you are using to start VPN
+2. Use another template qube that has a working `notify-send` or find proper guide and make your current template run `notify-send` work properly.
