# Upgrading Fedora TemplateVMs
|
|
|
|
This page provides instructions for performing an in-place upgrade of an installed [Fedora TemplateVM].
|
|
If you wish to install a new, unmodified Fedora TemplateVM instead of upgrading a template that is already installed in your system, please see the [Fedora TemplateVM] page instead. ([Learn more about the two options.][Fedora TemplateVM Upgrade])
|
|
|
|
|
|
## Summary instructions for standard Fedora TemplateVMs
|
|
|
|
**Note:** The prompt on each line indicates where each command should be entered: `dom0`, `fedora-<old>`, or `fedora-<new>`, where `<old>` is the Fedora version number *from* which you are upgrading, and `<new>` is the Fedora version number *to* which you are upgrading.
|
|
|
|
[user@dom0 ~]$ qvm-clone fedora-<old> fedora-<new>
|
|
[user@dom0 ~]$ truncate -s 5GB /var/tmp/template-upgrade-cache.img
|
|
[user@dom0 ~]$ qvm-run -a fedora-<new> gnome-terminal
|
|
[user@dom0 ~]$ dev=$(sudo losetup -f --show /var/tmp/template-upgrade-cache.img)
|
|
[user@dom0 ~]$ qvm-block attach fedora-<new> dom0:${dev##*/}
|
|
[user@fedora-<new> ~]$ sudo mkfs.ext4 /dev/xvdi
|
|
[user@fedora-<new> ~]$ sudo mount /dev/xvdi /mnt/removable
|
|
[user@fedora-<new> ~]$ sudo dnf clean all
|
|
[user@fedora-<new> ~]$ sudo dnf --releasever=<new> --setopt=cachedir=/mnt/removable --best --allowerasing distro-sync
|
|
[user@dom0 ~]$ qvm-shutdown fedora-<new>
|
|
[user@dom0 ~]$ sudo losetup -d $dev
|
|
[user@dom0 ~]$ rm /var/tmp/template-upgrade-cache.img
|
|
|
|
**Recommended:** [Switch everything that was set to the old template to the new template.][switch]
|
|
|
|
|
|
## Detailed instructions for standard Fedora TemplateVMs
|
|
|
|
These instructions will show you how to upgrade the standard Fedora TemplateVM.
|
|
The same general procedure may be used to upgrade any template based on the standard Fedora TemplateVM.
|
|
|
|
**Note:** The prompt on each line indicates where each command should be entered: `dom0`, `fedora-<old>`, or `fedora-<new>`, where `<old>` is the Fedora version number *from* which you are upgrading, and `<new>` is the Fedora version number *to* which you are upgrading.
|
|
|
|
1. Ensure the existing template is not running.
|
|
|
|
[user@dom0 ~]$ qvm-shutdown fedora-<old>
|
|
|
|
2. Clone the existing template and start a terminal in the new template.
|
|
|
|
[user@dom0 ~]$ qvm-clone fedora-<old> fedora-<new>
|
|
[user@dom0 ~]$ qvm-run -a fedora-<new> gnome-terminal
|
|
|
|
3. Attempt the upgrade process in the new template.
|
|
|
|
[user@fedora-<new> ~]$ sudo dnf clean all
|
|
[user@fedora-<new> ~]$ sudo dnf --releasever=<new> distro-sync --best --allowerasing
|
|
|
|
**Note:** `dnf` might ask you to approve importing a new package signing key.
|
|
For example, you might see a prompt like this one:
|
|
|
|
warning: /mnt/removable/updates-0b4cc238d1aa4ffe/packages/example-package.fc<new>.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID XXXXXXXX: NOKEY
|
|
Importing GPG key 0xXXXXXXXX:
|
|
Userid : "Fedora <new> (<new>) <fedora-<new>@fedoraproject.org>"
|
|
Fingerprint: XXXX XXXX XXXX XXXX XXXX XXXX XXXX XXXX XXXX XXXX
|
|
From : /etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-<new>-x86_64
|
|
Is this ok [y/N]: y
|
|
|
|
This key was already checked when it was installed (notice that the "From" line refers to a location on your local disk), so you can safely say yes to this prompt.
|
|
|
|
**Note:** If you encounter no errors, proceed to step 4.
|
|
If you do encounter errors, see the next two points first.
|
|
|
|
* If `dnf` reports that you do not have enough free disk space to proceed
|
|
with the upgrade process, create an empty file in dom0 to use as a cache
|
|
and attach it to the template as a virtual disk.
|
|
|
|
[user@dom0 ~]$ truncate -s 5GB /var/tmp/template-upgrade-cache.img
|
|
[user@dom0 ~]$ dev=$(sudo losetup -f --show /var/tmp/template-upgrade-cache.img)
|
|
[user@dom0 ~]$ qvm-block attach fedora-<new> dom0:${dev##*/}
|
|
|
|
Then reattempt the upgrade process, but this time use the virtual disk as a cache.
|
|
|
|
[user@fedora-<new> ~]$ sudo mkfs.ext4 /dev/xvdi
|
|
[user@fedora-<new> ~]$ sudo mount /dev/xvdi /mnt/removable
|
|
[user@fedora-<new> ~]$ sudo dnf clean all
|
|
[user@fedora-<new> ~]$ sudo dnf --releasever=<new> --setopt=cachedir=/mnt/removable --best --allowerasing distro-sync
|
|
|
|
If this attempt is successful, proceed to step 4.
|
|
|
|
* `dnf` may complain:
|
|
|
|
At least X MB more space needed on the / filesystem.
|
|
|
|
In this case, one option is to [resize the TemplateVM's disk image][resize-disk-image] before reattempting the upgrade process.
|
|
(See [Additional Information] below for other options.)
|
|
|
|
4. Check that you are on the correct (new) Fedora release.
|
|
|
|
[user@fedora-<new> ~]$ cat /etc/fedora-release
|
|
|
|
5. (Optional) Trim the new template.
|
|
(This should [no longer be necessary][template-notes], but it does not hurt.
|
|
Some users have [reported][5055] that it makes a difference.)
|
|
|
|
[user@fedora-<new> ~]$ sudo fstrim -av
|
|
[user@dom0 ~]$ qvm-shutdown fedora-<new>
|
|
[user@dom0 ~]$ qvm-start fedora-<new>
|
|
[user@fedora-<new> ~]$ sudo fstrim -av
|
|
|
|
6. Shut down the new TemplateVM.
|
|
|
|
[user@dom0 ~]$ qvm-shutdown fedora-<new>
|
|
|
|
7. Remove the cache file, if you created one.
|
|
|
|
[user@dom0 ~]$ sudo losetup -d $dev
|
|
[user@dom0 ~]$ rm /var/tmp/template-upgrade-cache.img
|
|
|
|
8. (Recommended) [Switch everything that was set to the old template to the new template.][switch]
|
|
|
|
9. (Optional) Make the new template the global default.
|
|
|
|
[user@dom0 ~]$ qubes-prefs --set fedora-<new>
|
|
|
|
10. (Optional) Remove the old template.
|
|
(Make sure to type the name of the old template, not the new one.)
|
|
|
|
[user@dom0 ~]$ sudo dnf remove qubes-template-fedora-<old>
|
|
|
|
|
|
## Summary instructions for Fedora Minimal TemplateVMs
|
|
|
|
**Note:** The prompt on each line indicates where each command should be entered: `dom0`, `fedora-<old>`, or `fedora-<new>`, where `<old>` is the Fedora version number *from* which you are upgrading, and `<new>` is the Fedora version number *to* which you are upgrading.
|
|
|
|
[user@dom0 ~]$ qvm-clone fedora-<old>-minimal fedora-<new>-minimal
|
|
[user@dom0 ~]$ qvm-run -u root -a fedora-<new>-minimal xterm
|
|
[root@fedora-<new>-minimal ~]# dnf clean all
|
|
[user@fedora-<new>-minimal ~]# dnf --releasever=<new> --best --allowerasing distro-sync
|
|
[user@fedora-<new>-minimal ~]# fstrim -v /
|
|
|
|
(Shut down TemplateVM by any normal means.)
|
|
|
|
(If you encounter insufficient space issues, you may need to use the methods described for the standard template above.)
|
|
|
|
|
|
## StandaloneVMs
|
|
|
|
The procedure for upgrading a Fedora [StandaloneVM] is the same as for a TemplateVM.
|
|
|
|
|
|
## Release-specific notes
|
|
|
|
This section contains notes about upgrading to specific releases.
|
|
|
|
|
|
### Fedora 30
|
|
|
|
If your RPM Fusion repositories are **disabled** when you upgrade a TemplateVM to 30, all RPM Fusion packages and RPM Fusion repo definitions will be removed from that TemplateVM.
|
|
If your RPM Fusion repositories are **enabled** when upgrading, all RPM Fusion packages and repo definitions will be retained and updated as expected.
|
|
For most users, this behavior should not cause a problem, since a TemplateVM in which the RPM Fusion repos are disabled is probably a TemplateVM in which you never wish to use them.
|
|
However, if you wish to have the RPM Fusion repo definitions after upgrading in a TemplateVM in which they are currently disabled, you may wish to temporarily enable them prior to upgrading or manually create, copy, or download them after upgrading.
|
|
|
|
|
|
### End-of-life (EOL) releases
|
|
|
|
We strongly recommend against using any Fedora release that has reached [end-of-life (EOL)].
|
|
|
|
|
|
## Additional information
|
|
|
|
As mentioned above, you may encounter the following `dnf` error:
|
|
|
|
At least X MB more space needed on the / filesystem.
|
|
|
|
In this case, you have several options:
|
|
|
|
1. [Increase the TemplateVM's disk image size][resize-disk-image].
|
|
This is the solution mentioned in the main instructions above.
|
|
2. Delete files in order to free up space. One way to do this is by uninstalling packages.
|
|
You may then reinstall them again after you finish the upgrade process, if desired).
|
|
However, you may end up having to increase the disk image size anyway (see previous option).
|
|
3. Do the upgrade in parts, e.g., by using package groups.
|
|
(First upgrade `@core` packages, then the rest.)
|
|
4. Do not perform an in-place upgrade, see [Upgrading Fedora TemplateVMs].
