Upgrading the Fedora 26 Template to Fedora 27
|
|
=============================================
|
|
|
|
This page provides instructions for performing an in-place upgrade of an
|
|
installed Fedora 26 [TemplateVM] to Fedora 27. If you wish to install a new,
|
|
unmodified Fedora 27 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 25 TemplateVM to
|
|
Fedora 27. Simply start by cloning `fedora-25` instead of `fedora-26` in the
|
|
instructions below.
|
|
|
|
|
|
Important information regarding RPM Fusion repos
|
|
------------------------------------------------
|
|
|
|
If your RPM Fusion repositories are **disabled** when you upgrade a TemplateVM from Fedora 26 to 27, 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 26 Template to Fedora 27 ###
|
|
|
|
**Note:** The prompt on each line indicates where each command should be entered
|
|
(`@dom0` or `@fedora-27`).
|
|
|
|
[user@dom0 ~]$ qvm-clone fedora-26 fedora-27
|
|
[user@dom0 ~]$ truncate -s 5GB /var/tmp/template-upgrade-cache.img
|
|
[user@dom0 ~]$ qvm-run -a fedora-27 gnome-terminal
|
|
[user@dom0 ~]$ dev=$(sudo losetup -f --show /var/tmp/template-upgrade-cache.img)
|
|
[user@dom0 ~]$ qvm-block attach fedora-27 dom0:${dev##*/}
|
|
[user@fedora-27 ~]$ sudo mkfs.ext4 /dev/xvdi
|
|
[user@fedora-27 ~]$ sudo mount /dev/xvdi /mnt/removable
|
|
[user@fedora-27 ~]$ sudo dnf clean all
|
|
[user@fedora-27 ~]$ sudo dnf --releasever=27 --setopt=cachedir=/mnt/removable --best --allowerasing distro-sync
|
|
[user@fedora-27 ~]$ 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 26 Template to Fedora 27 ###
|
|
|
|
These instructions will show you how to upgrade the standard Fedora 26
|
|
TemplateVM to Fedora 27. The same general procedure may be used to upgrade any
|
|
template based on the standard Fedora 26 template.
|
|
|
|
**Note:** The command-line prompt on each line indicates where each command
|
|
should be entered (`@dom0` or `@fedora-27`).
|
|
|
|
1. Ensure the existing template is not running.
|
|
|
|
[user@dom0 ~]$ qvm-shutdown fedora-26
|
|
|
|
2. Clone the existing template and start a terminal in the new template.
|
|
|
|
[user@dom0 ~]$ qvm-clone fedora-26 fedora-27
|
|
[user@dom0 ~]$ qvm-run -a fedora-27 gnome-terminal
|
|
|
|
3. Attempt the upgrade process in the new template.
|
|
|
|
[user@fedora-27 ~]$ sudo dnf clean all
|
|
[user@fedora-27 ~]$ sudo dnf --releasever=27 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: /var/cache/dnf/fedora-d02ca361e1b58501/packages/python2-babel-2.3.4-1.fc27.noarch.rpm: Header V3 RSA/SHA256 Signature, key ID f5282ee4: NOKEY
|
|
Importing GPG key 0xF5282EE4:
|
|
Userid : "Fedora (27) <fedora-27-primary@fedoraproject.org>"
|
|
Fingerprint: 860E 19B0 AFA8 00A1 7518 81A6 F55E 7430 F528 2EE4
|
|
From : /etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-27-x86_64
|
|
Is this ok [y/N]:
|
|
|
|
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-27 dom0:${dev##*/}
|
|
|
|
Then reattempt the upgrade process, but this time use the virtual disk
|
|
as a cache.
|
|
|
|
[user@fedora-27 ~]$ sudo mkfs.ext4 /dev/xvdi
|
|
[user@fedora-27 ~]$ sudo mount /dev/xvdi /mnt/removable
|
|
[user@fedora-27 ~]$ sudo dnf clean all
|
|
[user@fedora-27 ~]$ sudo dnf --releasever=27 --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. Trim the new template.
|
|
|
|
[user@fedora-27 ~]$ sudo fstrim -v /
|
|
|
|
5. Shut down the new TemplateVM (from the command-line or Qubes VM Manager).
|
|
|
|
[user@dom0 ~]$ qvm-shutdown fedora-27
|
|
|
|
6. Remove the cache file, if you created one.
|
|
|
|
[user@dom0 ~]$ sudo losetup -d $dev
|
|
[user@dom0 ~]$ rm /var/tmp/template-upgrade-cache.img
|
|
|
|
7. (Recommended) [Switch everything that was set to the old template to the new
|
|
template.][switching]
|
|
|
|
8. (Optional) Remove the old template. (Make sure to type `fedora-26`, not
|
|
`fedora-27`.)
|
|
|
|
[user@dom0 ~]$ sudo dnf remove qubes-template-fedora-26
|
|
|
|
|
|
### Upgrading StandaloneVMs ###
|
|
|
|
The procedure for upgrading a StandaloneVM from Fedora 26 to Fedora 27 is the
|
|
same as for a TemplateVM.
|
|
|
|
|
|
### Summary: Upgrading the Minimal Fedora 26 Template to Fedora 27 ###
|
|
|
|
**Note:** The prompt on each line indicates where each command should be entered
|
|
(`@dom0` or `@fedora-27`).
|
|
|
|
[user@dom0 ~]$ qvm-clone fedora-26-minimal fedora-27-minimal
|
|
[user@dom0 ~]$ qvm-run -u root -a fedora-27-minimal xterm
|
|
[root@fedora-27-minimal ~]# dnf clean all
|
|
[user@fedora-27-minimal ~]# dnf --releasever=27 --best --allowerasing distro-sync
|
|
[user@fedora-27-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][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 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
|
