# These instructions are for Qubes 4.0.? and 4.1.?
|
||||
|
||||
Archlinux template building instructions
|
||||
===========================================
|
||||
### 0. Installing the Fedora 32 Minimal template
|
||||
#### Open a terminal in Dom0
|
||||
|
||||
**These are the instructions for Qubes 4.0. They will take you step by step through the entire process start to finish**
|
||||
Large download (~639MB); if using 'sys-whonix' as the Dom0 UpdateVM then temporarily swap to 'sys-firewall' (to speed-up download speeds).
|
||||
```console
|
||||
# qubes-dom0-update qubes-template-fedora-32-minimal
|
||||
```
|
||||
Keep in mind what Qubes OS version your installation is; used when building Qubes Components and Template(s).
|
||||
```console
|
||||
# cat /etc/qubes-release
|
||||
```
|
||||
```
|
||||
# qvm-run -u root fedora-32-minimal xterm
|
||||
# dnf install qubes-core-agent-passwordless-root qubes-core-agent-networking iproute
|
||||
# exit
|
||||
```
|
||||
|
||||
1: Create and configure a qube for template building
|
||||
------------------------------------------------------------
|
||||
* The qube should be based on a Fedora template. I named the qube
|
||||
`build-archlinux2`, based on the minimal Fedora template.
|
||||
___
|
||||
### 1. Open a non-root ($) terminal in the 'fedora-32-minimal' TemplateVM.
|
||||
> **How to see whether the `'GNUMAKEFLAGS'` or `'MAKEFLAGS'` environment variable is used: \
|
||||
`$ strings /usr/bin/make | grep MAKEFLAGS` \
|
||||
GNU Make's `-l` set to same value as `-j` prevents CPU overcommitment.**
|
||||
|
||||
* `#`Edit: `/etc/profile.d/99-makeflags.sh`
|
||||
```sh
|
||||
export GNUMAKEFLAGS="-j$(nproc) -l$(nproc)"
|
||||
export MAKEFLAGS="-j$(nproc) -l$(nproc)"
|
||||
```
|
||||
> **The StandaloneVM type cannot build the Arch Linux (minimal or not) template currently, as its Makefiles and Scripts only fully accomodate for the AppVM type's set of filesystem permissions.**
|
||||
|
||||
|
||||
|
||||
* Ensure there is at least 15GB of free space in the private storage.
|
||||
* Allow at least 15GB of space in the Qube's private storage, then run the following commands:
|
||||
```console
|
||||
$ qvm-prefs build-archlinux2 vcpus $(nproc)
|
||||
$ qvm-prefs build-archlinux2 memory 4000
|
||||
$ qvm-prefs build-archlinux2 maxmem 4000
|
||||
```
|
||||
> **`nproc` specified the number of CPU logical cores it detected, meaning memory usage will increase for compilations that utilize the additional logical cores. For building the 'archlinux-minimal' template, 4000MB should be plenty.**
|
||||
|
||||
|
||||
|
||||
> **"System storage max. size" is allocated from the TemplateVM chosen.**
|
||||
|
||||
2: Create GitHub Account (optional)
|
||||
-------------------------------------------
|
||||
* It can be helpful. Creating only a basic account is all that is needed. This will allow you to help, going forward, with the Qubes project. You could be help edit errors in documentation. It can also be of use building other templates.
|
||||
* Create user account here https://github.com
|
||||
___
|
||||
### 2. Create a GitHub account
|
||||
<details><summary>Details</summary>
|
||||
|
||||
**This is a community effort in expanding the Qubes OS project. If you can help this effort out, do so for yourself and others.**
|
||||
|
||||
> **This is an optional step.**
|
||||
|
||||
|
||||
|
||||
3: Install necessary packages to `build-archlinux2` qube for "Qubes Automated Build System"
|
||||
-----------------------------------------------------------------------------------------------
|
||||
```shell_session
|
||||
# dnf install git make
|
||||
```
|
||||
</details>
|
||||
|
||||
4: Downloading and verifying the integrity of the "Qubes Automated Build System"
|
||||
---------------------------------------------------------------------------------
|
||||
* Import the Qubes master key
|
||||
```shell_session
|
||||
$ gpg --import /usr/share/qubes/qubes-master-key.asc
|
||||
___
|
||||
### 3. Downloading and verifying the integrity of the "Qubes Automated Build System"
|
||||
#### Open a terminal in the `build-archlinux2` Qube
|
||||
* Set terminal size to 30 lines and 100 columns; ensures text from **qubes-builder**'s setup script isn't cut-off.
|
||||
```console
|
||||
$ resize -s 30 100
|
||||
```
|
||||
* Verify its fingerprint, set as 'trusted'. [This is described here](https://www.qubes-os.org/doc/VerifyingSignatures).
|
||||
* Download the Qubes developers' keys.
|
||||
```shell_session
|
||||
$ wget https://keys.qubes-os.org/keys/qubes-developers-keys.asc
|
||||
$ gpg --import qubes-developers-keys.asc
|
||||
* Install initial dependencies without user confirmation.
|
||||
```console
|
||||
# dnf install -y git make
|
||||
```
|
||||
* Import and verify the Qubes master key; [to understand the purpose of GPG (a frontend for OpenPGP)](https://www.qubes-os.org/security/verifying-signatures/).
|
||||
```console
|
||||
$ gpg2 --import /usr/share/qubes/qubes-master-key.asc
|
||||
$ gpg2 --edit-key 0x427F11FD0FAA4B080123F01CDDFA1A3E36879494
|
||||
```
|
||||
```

|
||||
|
||||
* Download the latest stable qubes-builder repository:
|
||||
```shell_session
|
||||
$ git clone https://github.com/QubesOS/qubes-builder.git /home/user/qubes-builder/

```
|
||||
* Verify the integrity of the downloaded repository. The last line should read `gpg: Good signature from`...
|
||||
```shell_session
|
||||
$ cd /home/user/qubes-builder/
|
||||
* Download then import the Qubes developers' keys:
|
||||
```console
|
||||
$ curl -O https://keys.qubes-os.org/keys/qubes-developers-keys.asc
|
||||
$ gpg2 --import qubes-developers-keys.asc

```
|
||||
|
||||
5: Run the 'setup' script to build the builder.conf file
|
||||
-------------------------------------------------------------
|
||||
___
|
||||
### 4. Configure the `builder.conf` file
|
||||
> **The manual way is copying an example config like `$HOME/qubes-builder/example-configs/qubes-os-r4.0.conf` to `$HOME/qubes-builder/builder.conf`, then editing that copied file.**
|
||||
|
||||
( The manual way would be to copy an example config like '**/home/user/qubes-builder/example-configs/qubes-os-r4.0.conf**' to '**/home/user/qubes-builder/builder.conf**' and edit the file )
|
||||
* Run the 'setup' script located in '**/home/user/qubes-builder/**' Make sure you are in directory '**qubes-builder**'
|
||||
```shell_session
|

### 5. Make all the require Qubes components
|
||||
* Required before proceeding:
|
||||
```console
|
||||
$ make remount
|
||||
$ make install-deps
|
||||
$ make get-sources
|
||||
```
|
||||
|
||||
7: Make all the require Qubes Components
|
||||
------------------------------------------------
|
||||
* **Note:** You can run a single command to build all the Qubes components or you can run them each individually.
|
||||
Both ways below:
|
||||
* Single command to build all Qubes components together: (this command can take a long time to process depending of your pc proccessing power)
|
||||
```shell_session
|
||||
* {Preferred} Building all Qubes components (this can take a long time):
|
||||
```console
|
||||
$ make qubes-vm
|
||||
```
|
||||
* These are the indivual component 'make' commands:
|
||||
```shell_session
|
||||
* {Debugging/development} Individual 'make' commands for Qubes components:
|
||||
```console
|
||||
$ make vmm-xen-vm
|
||||
$ make core-vchan-xen-vm
|
||||
$ make core-qubesdb-vm
|
||||
@ -157,73 +248,71 @@ $ make gui-agent-linux-vm
|
||||
$ make app-linux-split-gpg-vm
|
||||
```
|
||||
|
||||
8: Make the actual Archlinux template
|
||||
----------------------------------------
|
||||
```shell_session
|
||||
___
|
||||
### 6. Build the actual Arch Linux template
|
||||
```console
|
||||
$ make template
|
||||
```
|
||||
|
||||
9: Transfer Template into Dom0
|
||||
----------------------------------
|
||||
* You need to ensure these two files are in the '**noarch**' directory
|
||||
```shell_session
|
||||
$ cd /home/user/qubes-builder/qubes-src/linux-template-builder/rpm/
|
||||
___
|
||||
### 7. Transfer Arch Linux template into Dom0
|
||||
* You need to ensure these two files are in the `noarch` directory:
|
||||
```console
|
||||
$ cd $HOME/qubes-builder/qubes-src/linux-template-builder/rpm/
|
||||
$ ls
|
||||
install-templates.sh
|
||||
$ cd noarch
|
||||
$ ls
|
||||
qubes-template-archlinux-X.X.X-XXXXXXXXXXXX.noarch.rpm
|
||||
qubes-template-archlinux-*.*.*-*.noarch.rpm
|
||||
```
|
||||
|
||||
|
||||
|
||||
* **Transfer the install-templates.sh script file into Dom0**
|
||||
*Note: as there is not a typical file transfer method for Dom0, for security reasons, this less than simple transfer function has to be used*
|
||||
* Switch to Dom0 and open a terminal window.
|
||||
```shell_session
|
||||
$ qvm-run --pass-io build-archlinux2 'cat /home/user/qubes-builder/qubes-src/linux-template-builder/rpm/install-templates.sh' > install-templates.sh
|
||||
> **There are more steps involved for file transfering to Dom0 since it's considered unsafe. \
|
||||
You accept full responsibility if Dom0 is compromised due to this file transfer.**
|
||||
* Open a terminal in Dom0, and execute the following commands:
|
||||
```console
|
||||
$ qvm-run --pass-io build-archlinux2 'cat $HOME/qubes-builder/qubes-src/linux-template-builder/rpm/install-templates.sh' > install-templates.sh
|
||||
$ chmod +x install-templates.sh
|
||||
$ ./install-templates.sh
|
||||
```
|
||||
* If everything went correct there should be a Archlinux template listed in your Qubes Manager
|
||||
* If the build process went smoothly, the 'archlinux' and/or 'archlinux-minimal' template will be listed in Qubes Manager.
|
||||
|
||||
Debugging the build process
|
||||
===============================
|
||||
Archlinux use bleeding edge version of everything, so it is usually the
|
||||
first template to break when new software version came out.
|
||||
So an important point is to understand how to debug the template, how to fix
|
||||
it, and then do a pull request :).
|
||||
[My personal building script is here](https://github.com/Qubes-Community/Contents/blob/master/code/OS-administration/build-archlinux.sh).
|
||||
___
|
||||
### Debugging the build process
|
||||
Arch Linux is a [rolling](https://en.wikipedia.org/wiki/Rolling_release) distro, making it a fragile template for Qubes.
|
||||
It's important to understand how to debug Qubes templates, fix, then do a pull request.
|
||||
|
||||
The most important part about this script is where to add custom code that is not in the QubesOS repositories
|
||||
[neowutran's semi-automated Arch Linux template builder script](https://github.com/Qubes-Community/Contents/blob/master/code/OS-administration/build-archlinux.sh). \
|
||||
The most important part about this script is where to add custom code that is not in the QubesOS repositories.
|
||||
|
||||
<!-- Whoever made these lines need to clarify what this is about.
|
||||
|
||||
After the command:
|
||||
```shell_session
|
||||
```console
|
||||
$ make get-sources
|
||||
```
|
||||
|
||||
And before the command:
|
||||
```shell_session
|
||||
```console
|
||||
$ make qubes-vm
|
||||
```
|
||||
-->
|
||||
|
||||
you can put your custom code by replacing the qubes-src/ directories.

You can put your custom code by replacing the `qubes-src/` directories.
|
||||
For example:

The xorg-server package was probably updated to a version greater than 1.20.7.

Nor a fix nor a minor version change is likely to break things.

"qubes-gui-agent-linux".
|

Let's clone "qubes-gui-agent-linux", be sure to checkout the correct

branch (example: `release4.0` instead of master ), and then edit the **/archlinux/PKGBUILD**
|

to do the modification you want to try.
|
||||
In your building script, right before the "make qubes-vm", remove the existing
|
||||
"gui-agent-linux" folder, and replace it with your own.
|
||||
Example, add this to the script
|
||||
|
||||
```shell_session
|

$ rm -Rf "~/qubes-builder/qubes-src/gui-agent-linux/"
|
||||
$ cp -R ~/qubes-gui-agent-linux "~/qubes-builder/qubes-src/gui-agent-linux"
|
||||
So the **/archlinux/PKGBUILD** file of the repository "qubes-gui-agent-linux" requires modification. \
|
||||
Git clone "qubes-gui-agent-linux", git checkout to the correct branch (example: `release4.0` instead of master), and then attempt a modification on the **/archlinux/PKGBUILD** file. \
|
||||
In your building script, right before the "make qubes-vm", remove the existing "gui-agent-linux" folder and replace it with your own.

||||
Example, add this to the script:
|

```sh
|
||||
rm -Rf "~/qubes-builder/qubes-src/gui-agent-linux/"
|
||||
cp -R ~/qubes-gui-agent-linux "~/qubes-builder/qubes-src/gui-agent-linux"
|
||||
```
|
||||
and retry to build the template.
|
||||
If it build successfully and that the template work as expected, do a pull request on github to share your fix.
|
||||
Then try building the template.
|
||||
If the template built successfully and works as expected, do a pull request on GitHub to share your fix(es).

This error is caused by Arch Linux having a newer version of PulseAudio than the PulseAudio headers imported by the Qubes team.

It can be fixed by downloading the new version of the headers, and rebuilding.

This solution prevents any breaking API changes from going silently unoticed.
|

```
|

$ #replace 14.2 with your version here (remove downstream -PATCH suffix (14.2-1 -> 14.2))

Debugging the qube runtime
|

================================================================
|
||||
If you are able to launch a terminal and execute command, just use your usual

||||
archlinux-fu to fix the issue.
|
||||
If you are not able to launch a terminal, then, shutdown the qube, create a new
|
||||
DisposableVM, [mount the Archlinux disk in the DisposableVM](https://www.qubes-os.org/doc/mount-lvm-image/), chroot to it, and then use
|

your archlinux-fu.

Creating a archlinux repository
|
||||
===========================
|
||||
|
||||
### Creating a archlinux repository
|
||||
Once the template have been build, you could use the generated archlinux packages to create your own archlinux repository for QubesOS packages.
|
||||
You need to:
|
||||
|
||||
* Sign the packages with your GPG key
|
||||
* Host the packages on your HTTP server
|
||||
|
||||
I will assume that you already have a working http server.
|
||||
So you need to sign the packages and transmit everything to the qubes that will upload them to your http server.
|
||||
The script `update-remote-repo.sh` of the qubes-builder-archlinux repository can do that.
|
||||
I will assume that you already have a working HTTP server. \
|
||||
So you need to sign the packages and transmit everything to the qubes that will upload them to your HTTP server.
|
||||
The script `update-remote-repo.sh` of the "qubes-builder-archlinux" repository can do that.
|
||||
Below, an example of code that sign the packages + template rpm file, and transmit everything to another qube.
|
||||
|
||||
```bash
|
||||
```sh
|
||||
$directory/qubes-src/builder-archlinux/update-remote-repo.sh
|
||||
rpmfile=$(ls -1 $directory/qubes-src/linux-template-builder/rpm/noarch/*.rpm | head -n 1)

Upload everything to your HTTP server, and you are good.

You can now modify the file `/etc/pacman.d/99-qubes-repository-4.0.conf` in your archlinux template to use your repository.

### About the package `qubes-vm-keyring`
|
||||
The goal of this package was to add a **`pacman`** source for the Qubes OS packages, and to set its maintainer GPG key as trusted.
|
||||
**There are binary packages available (unofficially):**
|
||||
* https://neowutran.ovh/qubes/vm-archlinux/pkgs (go up a directory for an Arch Linux template built for Qubes OS 4.0.3 only)

About the package `qubes-vm-keyring`
|
||||
=====================================
|
||||
The goal of this package was to add a `pacman` source for the Qubes OS packages, and to set the maintainer gpg key as trusted.
|
||||
Currently, no one want to provide binary packages.
|
||||
|
||||
**So this package is currently useless.**
|
||||
|
||||
If in the future, enough people think it is better to restart providing binary packages instead of the current "Do It Yourself" way, the gpg key and fingerprint of the new maintainer should be added in the files below:
|
||||
If the Qubes OS developers start providing binary packages themselves, the GPG key and fingerprint of the new maintainer(s) might be added in the files below:

### StandaloneVM stuff
|
||||
Having a StandaloneVM for building Qube distro templates would be safer than an AppVM, and wouldn't require reinstalling all dependencies after each VM reboot. \
|
||||
But if this wasn't chosen over AppVM by default, there must be downsides to a StandaloneVM I'm unable to think of from a lack of knowledge with Qubes' inner workings.
