Upgrading the Debian 8 Template
|
|
===============================
|
|
|
|
Disclaimer: Debian 9 (Stretch) is marked testing for a reason. You may notice stability problems when using it.
|
|
|
|
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-r3.list` before attempting the upgrade. Otherwise, your upgrade will [break](https://github.com/QubesOS/qubes-issues/issues/2418).
|

|
Summary: Upgrading a Debian 8 Template to Debian 9
|
|
--------------------------------------------------
|
|
|
|
[user@dom0 ~]$ qvm-clone debian-8 debian-9
|
|
[user@dom0 ~]$ qvm-run -a debian-9 gnome-terminal
|
|
[user@debian-9 ~]$ sudo sed -i 's/jessie/stretch/g' /etc/apt/sources.list
|
|
[user@debian-9 ~]$ sudo sed -i 's/jessie/stretch/g' /etc/apt/sources.list.d/qubes-r3.list
|
|
[user@debian-9 ~]$ sudo apt-get update && sudo apt-get dist-upgrade -y
|
|
[user@debian-9 ~]$ sudo apt-get autoremove
|
|
|
|
(Shut down TemplateVM by any normal means.)
|
|
|
|
[user@dom0 ~]$ qvm-trim-template debian-9
|
|
|
|
(Done.)
|
|
|
|
Detailed: Upgrading the Standard Debian 8 Template to Debian 9
|
|
--------------------------------------------------------------
|
|
|
|
These instructions will show you how to upgrade the standard Debian 8
|
|
TemplateVM to Debian 9. The same general procedure may be used to upgrade
|
|
any template based on the standard Debian 8 template.
|
|
|
|
1. Ensure the existing template is not running.
|
|
|
|
[user@dom0 ~]$ qvm-shutdown debian-8
|
|
|
|
2. Clone the existing template and start a terminal in the new template.
|
|
|
|
[user@dom0 ~]$ qvm-clone debian-8 debian-9
|
|
[user@dom0 ~]$ qvm-run -a debian-9 gnome-terminal
|
|
|
|
3. Update your apt repositories to use stretch instead of jessie
|
|
(This can be done manually with a text editor, but sed can be used to
|
|
automatically update the files.)
|
|
|
|
[user@debian-9 ~]$ sudo sed -i 's/jessie/stretch/g' /etc/apt/sources.list
|
|
[user@debian-9 ~]$ sudo sed -i 's/jessie/stretch/g' /etc/apt/sources.list.d/qubes-r3.list
|
|
|
|
4. Update the package lists and upgrade to Debian 9. During the process,
|
|
it will likely prompt to overwrite two files, qubes-r3.list and
|
|
pulse/client.conf. qubes-r3.list can be overwritten, while pulse/client.conf
|
|
need to left as the currently installed version.
|
|
|
|
[user@debian-9 ~]$ sudo apt-get update && sudo apt-get dist-upgrade -y
|
|
|
|
5. Remove unnecessary packages that were previously installed
|
|
|
|
[user@debian-9 ~]$ sudo apt-get autoremove
|
|
|
|
6. Shutdown the new TemplateVM via dom0 command line or Qubes VM Manager;
|
|
|
|
[user@dom0 ~]$ qvm-shutdown debian-9
|
|
|
|
7. Trim the new template (see **Compacting the Upgraded Template** for details
|
|
and other options).
|
|
|
|
[user@dom0 ~]$ qvm-trim-template debian-9
|
|
|
|
8. (Optional) Remove the old default template.
|
|
|
|
[user@dom0 ~]$ sudo yum remove qubes-template-debian-8
|
|
|
|
|
|
Compacting the Upgraded Template
|
|
--------------------------------
|
|
|
|
Neither `fstrim` nor the `discard` mount option works on the TemplateVM's root
|
|
filesystem, so when a file is removed in the template, space is not freed in
|
|
dom0. This means that the template will use about twice as much space as is
|
|
really necessary after upgrading.
|
|
|
|
If you have at least `qubes-core-dom0-2.1.68` installed or are on Qubes R3.0,
|
|
you can use the `qvm-trim-template` tool:
|
|
|
|
[user@dom0 ~]$ qvm-trim-template debian-9
|
|
|
|
If you do not have `qubes-core-dom0-2.1.68` or are on older Qubes version, you can
|
|
compact the `root.img` manually. To do this, you will need about 15GB (the
|
|
TemplateVM's max size + the actually used space there) free space in dom0.
|
|
|
|
1. Start the template and fill all the free space with zeros, for example
|
|
with:
|
|
|
|
[user@debian-9 ~]$ dd if=/dev/zero of=/var/tmp/zero
|
|
|
|
2. Wait for the "No space left on device" error. Then:
|
|
|
|
[user@debian-9 ~]$ rm -f /var/tmp/zero
|
|
|
|
3. Shut down the template and all VMs based on it. Then:
|
|
|
|
[user@dom0 ~]$ cd /var/lib/qubes/vm-templates/debian-9
|
|
[user@dom0 ~]$ cp --sparse=always root.img root.img.new
|
|
[user@dom0 ~]$ mv root.img.new root.img
|
|
|
|
Additional Information
|
|
----------------------
|
|
|
|
It should be noted that Debian 9 (Stretch) is currently marked testing and
|
|
should be treat as such. For projects that need absolute stability, upgrading
|
|
may not be the best option.
|
|
|
|
Debian Stretch packages were first made available in the Qubes R3.1 repositories.
|
|
|
|
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-r3.list file and uncommenting the Qubes Updates Candidates repo.
|
|
|
|
User-initiated updates/upgrades may not run when a templateVM first starts. This is due to a new Debian config setting that attempts to update automatically; it can be [disabled with](https://github.com/QubesOS/qubes-issues/issues/2621) `systemctl disable apt-daily.timer`.
