Upgrading the Fedora 28 Template to Fedora 29

This page provides instructions for performing an in-place upgrade of an installed Fedora 28 TemplateVM to Fedora 29. If you wish to install a new, unmodified Fedora 29 template instead of upgrading a template that is already installed in your system, please see the Fedora TemplateVM page instead.

These instructions can also be used to upgrade a Fedora 26 TemplateVM to Fedora 29. Simply start by cloning fedora-26 instead of fedora-28 in the instructions below.

Important information regarding RPM Fusion repos

If your RPM Fusion repositories are disabled when you upgrade a TemplateVM from Fedora 28 to 29, 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.

Summary: Upgrading the Standard Fedora 28 Template to Fedora 29

Note: The prompt on each line indicates where each command should be entered (@dom0 or @fedora-29).

    [user@dom0 ~]$ qvm-clone fedora-28 fedora-29
    [user@dom0 ~]$ truncate -s 5GB /var/tmp/template-upgrade-cache.img
    [user@dom0 ~]$ qvm-run -a fedora-29 gnome-terminal
    [user@dom0 ~]$ dev=$(sudo losetup -f --show /var/tmp/template-upgrade-cache.img)
    [user@dom0 ~]$ qvm-block attach fedora-29 dom0:${dev##*/}
    [user@fedora-29 ~]$ sudo mkfs.ext4 /dev/xvdi
    [user@fedora-29 ~]$ sudo mount /dev/xvdi /mnt/removable
    [user@fedora-29 ~]$ sudo dnf clean all
    [user@fedora-29 ~]$ sudo dnf --releasever=29 --setopt=cachedir=/mnt/removable --best --allowerasing distro-sync
    [user@fedora-29 ~]$ sudo fstrim -v /

(Shut down TemplateVM by any normal means.)

    [user@dom0 ~]$ sudo losetup -d $dev
    [user@dom0 ~]$ rm /var/tmp/template-upgrade-cache.img

(Optional cleanup: Switch everything over to the new template and delete the old one. See instructions below for details.)

Detailed: Upgrading the Standard Fedora 28 Template to Fedora 29

These instructions will show you how to upgrade the standard Fedora 28 TemplateVM to Fedora 29. The same general procedure may be used to upgrade any template based on the standard Fedora 28 template.

Note: The command-line prompt on each line indicates where each command should be entered (@dom0 or @fedora-29).

1. Ensure the existing template is not running.

   [user@dom0 ~]$ qvm-shutdown fedora-28
   

2. Clone the existing template and start a terminal in the new template.

   [user@dom0 ~]$ qvm-clone fedora-28 fedora-29
   [user@dom0 ~]$ qvm-run -a fedora-29 gnome-terminal
   

3. Attempt the upgrade process in the new template.

   [user@fedora-29 ~]$ sudo dnf clean all
   [user@fedora-29 ~]$ sudo dnf --releasever=29 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/kernel-4.18.17-300.fc29.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID 429476b4: NOKEY
   Importing GPG key 0x429476B4:
    Userid     : "Fedora 29 (29) <fedora-29@fedoraproject.org>"
    Fingerprint: 5A03 B4DD 8254 ECA0 2FDA 1637 A20A A56B 4294 76B4
    From       : /etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-29-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-29 dom0:${dev##*/}
     

     Then reattempt the upgrade process, but this time use the virtual disk as a cache.

     [user@fedora-29 ~]$ sudo mkfs.ext4 /dev/xvdi
     [user@fedora-29 ~]$ sudo mount /dev/xvdi /mnt/removable
     [user@fedora-29 ~]$ sudo dnf clean all
     [user@fedora-29 ~]$ sudo dnf --releasever=29 --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 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-29 ~]$ cat /etc/fedora-release
   

5. Trim the new template.

   [user@fedora-29 ~]$ sudo fstrim -v /
   

6. Shut down the new TemplateVM (from the command-line or Qubes VM Manager).

   [user@dom0 ~]$ qvm-shutdown fedora-29
   

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.

9. (Optional) Remove the old template. (Make sure to type fedora-28, not fedora-29.)

   [user@dom0 ~]$ sudo dnf remove qubes-template-fedora-28
   

Upgrading StandaloneVMs

The procedure for upgrading a StandaloneVM from Fedora 28 to Fedora 29 is the same as for a TemplateVM.

Summary: Upgrading the Minimal Fedora 28 Template to Fedora 29

Note: The prompt on each line indicates where each command should be entered (@dom0 or @fedora-29).

    [user@dom0 ~]$ qvm-clone fedora-28-minimal fedora-29-minimal
    [user@dom0 ~]$ qvm-run -u root -a fedora-29-minimal xterm
    [root@fedora-29-minimal ~]# dnf clean all
    [user@fedora-29-minimal ~]# dnf --releasever=29 --best --allowerasing distro-sync
    [user@fedora-29-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.)

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. 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 reinstalling 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. Instead, simply download and install a new template package, then redo all desired template modifications.

   With regard to the last option, here are some useful messages from the mailing list which also apply to TemplateVM management and migration in general:
