How to upgrade a Fedora template in-place
|
||
=========================================
|
||
|
||
|
||
.. DANGER::
|
||
Warning: This page is intended for advanced users only. Most users
|
||
seeking to upgrade should instead install a new Fedora template.
|
||
Learn more about the two options here.
|
||
|
||
|
||
This page provides instructions for performing an in-place upgrade of an
|
||
installed :doc:`Fedora Template </user/templates/fedora/fedora>`. If you wish to
|
||
install a new, unmodified Fedora template instead of upgrading a
|
||
template that is already installed in your system, please see the
|
||
:doc:`Fedora Template </user/templates/fedora/fedora>` page instead. (:ref:`Learn more about the two options. <user/templates/fedora/fedora:upgrading>`)

||
Summary instructions for standard Fedora templates
|
||
--------------------------------------------------
|
||
|
||
|
||
**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.
|
||
|
||
.. code:: bash
|
||
|
||
[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
|
||
[user@dom0 ~]$ qvm-features fedora-<new> template-name fedora-<new>
|
||
|
||
|
||
**Recommended:** :ref:`Switch everything that was set to the old template to the new template. <user/templates/templates:switching>`
|
||
|
||
Detailed instructions for standard Fedora templates
|
||
---------------------------------------------------
|
||
|
||
|
||
These instructions will show you how to upgrade the standard Fedora
|
||
template. The same general procedure may be used to upgrade any template
|
||
based on the standard Fedora template.
|
||
|
||
**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.
|
||
|
||
.. code:: bash
|
||
|
||
[user@dom0 ~]$ qvm-shutdown fedora-<old>
|
||
|
||
|
||
2. Clone the existing template and start a terminal in the new
|
||
template.
|
||
|
||
.. code:: bash
|
||
|
||
[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.
|
||
|
||
.. code:: bash
|
||
|
||
[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:
|
||
|
||
.. code:: bash
|
||
|
||
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.
|
||
|
||
.. code:: bash
|
||
|
||
[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:${dev##*/}
|
||
|
||
Then reattempt the upgrade process, but this time use the virtual
|
||
disk as a cache.
|
||
|
||
.. code:: bash
|
||
|
||
[user@fedora-<new> ~]$ 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 :doc:`resize the template’s disk image </user/advanced-topics/resize-disk-image>` before reattempting the
|
||
upgrade process. (See `Additional Information <#additional-information>`__ below for other
|
||
options.)
|
||
|
||
|
||
|
||
4. Check that you are on the correct (new) Fedora release. Do this
|
||
check only after completing the upgrade process. This is *not* a
|
||
troubleshooting procedure for fixing download issues from the
|
||
repository. This check simply verifies that your clone has
|
||
successfully been upgraded.
|
||
|
||
.. code:: bash
|
||
|
||
[user@fedora-<new> ~]$ cat /etc/fedora-release
|
||
|
||
|
||
|
||
5. (Optional) Trim the new template. (This should :ref:`no longer be necessary <user/templates/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.)
|
||
|
||
.. code:: bash
|
||
|
||
[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 template.
|
||
|
||
.. code:: bash
|
||
|
||
[user@dom0 ~]$ qvm-shutdown fedora-<new>
|
||
|
||
|
||
7. Remove the cache file, if you created one.
|
||
|
||
.. code:: bash
|
||
|
||
[user@dom0 ~]$ sudo losetup -d $dev
|
||
[user@dom0 ~]$ rm /var/tmp/template-upgrade-cache.img
|
||
|
||
|
||
8. Set the template-name, which is used by the Qubes updater.
|
||
|
||
.. code:: bash
|
||
|
||
[user@dom0 ~]$ qvm-features fedora-<new> template-name fedora-<new>
|
||
|
||
|
||
9. (Recommended) :ref:`Switch everything that was set to the old template to the new template. <user/templates/templates:switching>`
|
||
|
||
10. (Optional) Make the new template the global default.
|
||
|
||
.. code:: bash
|
||
|
||
[user@dom0 ~]$ qubes-prefs --set default_template fedora-<new>
|
||
|
||
|
||
11. (Optional) :ref:`Uninstall the old template. <user/templates/templates:uninstalling>` Make sure that the
|
||
template you’re uninstalling is the old one, not the new one!
|
||
|
||
|
||

||
Summary instructions for Fedora Minimal templates
|
||
-------------------------------------------------
|
||
|
||
|
||
**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.
|
||
|
||
.. code:: bash
|
||
|
||
[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 /
|
||
[user@dom0 ~]$ qvm-features fedora-<new>-minimal template-name fedora-<new>
|
||
|
||
|
||
(Shut down template by any normal means.)
|
||
|
||
(If you encounter insufficient space issues, you may need to use the
|
||
methods described for the standard template above.)
|
||
|
||
Standalones
|
||
-----------
|
||
|
||
|
||
The procedure for upgrading a Fedora
|
||
:doc:`standalone </user/advanced-topics/standalones-and-hvms>` is the same as for a template.
|
||
|
||
Release-specific notes
|
||
----------------------
|
||
|
||
|
||
See the `news <https://www.qubes-os.org/news/>`__ announcement for each specific template
|
||
release for any important notices about that particular release.
|
||
|
||
End-of-life (EOL) releases
|
||
^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||
|
||
|
||
We strongly recommend against using any Fedora release that has reached
|
||
`end-of-life (EOL) <https://fedoraproject.org/wiki/End_of_life>`__. Also
|
||
see :doc:`supported releases </user/downloading-installing-upgrading/supported-releases>`.
|
||
|
||
Additional information
|
||
----------------------
|
||
|
||
|
||
As mentioned above, you may encounter the following ``dnf`` error:
|
||
|
||
.. code:: bash
|
||
|
||
At least X MB more space needed on the / filesystem.
|
||
|
||
|
||
|
||
In this case, you have several options:
|
||
|
||
1. :doc:`Increase the template’s disk image size </user/advanced-topics/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 :ref:`Upgrading Fedora templates <user/templates/fedora/fedora:upgrading>`.
