<b>Warning:</b> This page is intended for advanced users only. Most users seeking to upgrade should instead <a href="/doc/templates/debian/#installing">install a new Debian template</a>. Learn more about the two options <a href="/doc/templates/debian/#upgrading">here</a>.

This page provides instructions for performing an in-place upgrade of an installed [Debian Template](/doc/templates/debian/).
|
|
If you wish to install a new, unmodified Debian template instead of upgrading a template that is already installed in your system, please see the [Debian Template](/doc/templates/debian/) page instead. ([Learn more about the two options.](/doc/templates/debian/#upgrading))
|
|
|
|
In general, upgrading a Debian template follows the same process as [upgrading a native Debian system](https://wiki.debian.org/DebianUpgrade).
|
|
|
|
## Summary instructions for Debian templates
|
|
|
|
**Note:** The prompt on each line indicates where each command should be entered: `dom0`, `debian-<old>`, or `debian-<new>`, where `<old>` is the Debian version number *from* which you are upgrading, and `<new>` is the Debian version number *to* which you are upgrading.
|
|
|
|
```
|
|
[user@dom0 ~]$ qvm-clone debian-<old> debian-<new>
|
|
[user@dom0 ~]$ qvm-run -a debian-<new> gnome-terminal
|
|
[user@debian-<new> ~]$ sudo sed -i 's/<old-name>/<new-name>/g' /etc/apt/sources.list
|
|
[user@debian-<new> ~]$ sudo sed -i 's/<old-name>/<new-name>/g' /etc/apt/sources.list.d/qubes-r4.list
|
|
[user@debian-<new> ~]$ sudo apt update
|
|
[user@debian-<new> ~]$ sudo apt upgrade
|
|
[user@debian-<new> ~]$ sudo apt dist-upgrade
|
|
[user@dom0 ~]$ qvm-shutdown debian-<new>
|
|
```
|
|
|
|
**Recommended:** [Switch everything that was set to the old template to the new template.](/doc/templates/#switching)
|
|
|
|
## Detailed instructions for Debian templates
|
|
|
|
These instructions will show you how to upgrade Debian templates.
|
|
The same general procedure may be used to upgrade any template based on the standard Debian template.
|
|
|
|
**Note:** The prompt on each line indicates where each command should be entered: `dom0`, `debian-<old>`, or `debian-<new>`, where `<old>` is the Debian version number *from* which you are upgrading, and `<new>` is the Debian version number *to* which you are upgrading.
|
|
|
|
1. Ensure the existing template is not running.
|
|
|
|
```
|
|
[user@dom0 ~]$ qvm-shutdown debian-<old>
|
|
```
|
|
|
|
2. Clone the existing template and start a terminal in the new template.
|
|
|
|
```
|
|
[user@dom0 ~]$ qvm-clone debian-<old> debian-<new>
|
|
[user@dom0 ~]$ qvm-run -a debian-<new> gnome-terminal
|
|
```
|
|
|
|
3. Update your `apt` repositories to use the new release's code name instead of the old release's code name.
|
|
(This can be done manually with a text editor, but `sed` can be used to automatically update the files.)
|
|
|
|
```
|
|
[user@debian-<new> ~]$ sudo sed -i 's/<old-name>/<new-name>/g' /etc/apt/sources.list
|
|
[user@debian-<new> ~]$ sudo sed -i 's/<old-name>/<new-name>/g' /etc/apt/sources.list.d/qubes-r4.list
|
|
```
|
|
|
|
4. Update the package lists and upgrade.
|
|
During the process, it may prompt you to overwrite the file `qubes-r4.list`.
|
|
You should overwrite this file.
|
|
|
|
```
|
|
[user@debian-<new> ~]$ sudo apt update
|
|
[user@debian-<new> ~]$ sudo apt upgrade
|
|
[user@debian-<new> ~]$ sudo apt dist-upgrade
|
|
```
|
|
|
|
5. (Optional) Remove unnecessary packages that were previously installed.
|
|
|
|
```
|
|
[user@debian-<new> ~]$ sudo apt-get autoremove
|
|
```
|
|
|
|
6. (Optional) Clean cached packages from `/var/cache/apt`.
|
|
|
|
```
|
|
[user@debian-<new> ~]$ sudo apt-get clean
|
|
```
|
|
|
|
7. (Optional) Trim the new template.
|
|
(This should [no longer be necessary](/doc/templates/#important-notes), but it does not hurt.
|
|
Some users have [reported](https://github.com/QubesOS/qubes-issues/issues/5055) that it makes a difference.)
|
|
|
|
```
|
|
[user@debian-<new> ~]$ sudo fstrim -av
|
|
[user@dom0 ~]$ qvm-shutdown debian-<new>
|
|
[user@dom0 ~]$ qvm-start debian-<new>
|
|
[user@debian-<new> ~]$ sudo fstrim -av
|
|
```
|
|
|
|
8. Shut down the new template.
|
|
|
|
```
|
|
[user@dom0 ~]$ qvm-shutdown debian-<new>
|
|
```
|
|
|
|
9. (Recommended) [Switch everything that was set to the old template to the new template.](/doc/templates/#switching)
|
|
|
|
10. (Optional) Make the new template the global default.
|
|
|
|
```
|
|
[user@dom0 ~]$ qubes-prefs --set debian-<new>
|
|
```
|
|
|
|
11. (Optional) [Uninstall the old template.](/doc/templates/#uninstalling)
|
|
Make sure that the template you're uninstalling is the old one, not the new one!
|
|
|
|
## Standalones
|
|
|
|
The procedure for upgrading a Debian [standalone](/doc/standalone-and-hvm/) is the same as for a template.
|
|
|
|
## Release-specific notes
|
|
|
|
This section contains notes about upgrading to specific releases.
|
|
|
|
### Debian 10 ("Buster")
|
|
|
|
Please see [Debian's Buster upgrade instructions](https://www.debian.org/releases/buster/amd64/release-notes/ch-upgrading.en.html).
|
|
|
|
### Debian 9 ("Stretch")
|
|
|
|
* The upgrade process may prompt you to overwrite two files: `qubes-r4.list` and `pulse/client.conf`.
|
|
`qubes-r4.list` can be overwritten, but `pulse/client.conf` must be left as the currently-installed version.
|
|
|
|
* If sound is not working, you may need to enable the Qubes testing repository to get the testing version of `qubes-gui-agent`.
|
|
This can be done by editing the `/etc/apt/sources.list.d/qubes-r4.list` file and uncommenting the `Qubes Updates Candidates` repo.
|
|
|
|
* User-initiated updates/upgrades may not run when a template first starts.
|
|
This is due to a new Debian config setting that attempts to update automatically; it should be disabled with `sudo systemctl disable apt-daily.{service,timer}`.
|
|
|
|

Also see [Debian's Stretch upgrade instructions](https://www.debian.org/releases/stretch/amd64/release-notes/ch-upgrading.en.html).
|
|
|
|
### Debian 8 ("Jessie")
|
|
|
|
Please see [Debian's Jessie upgrade instructions](https://www.debian.org/releases/jessie/amd64/release-notes/ch-upgrading.en.html).
|
|
|
|
### End-of-life (EOL) releases
|
|
|
|
We strongly recommend against using any Debian release that has reached [end-of-life (EOL)](https://wiki.debian.org/DebianReleases#Production_Releases).
|
|
|
|
## Additional information
|
|
|
|
* Please note that, if you installed packages from one of the testing repositories, you must make sure that the repository is enabled in `/etc/apt/sources.list.d/qubes-r4.list` before attempting the upgrade.
|
|
Otherwise, your upgrade will [break](https://github.com/QubesOS/qubes-issues/issues/2418).
|
|
|
|
* By default, Qubes uses code names in the `apt` sources files, although the templates are referred to by release number.
|
|
Check the code names for the templates, and ensure you are aware of any changes you have made in the repository definitions.
