The same general procedure may be used to upgrade any +template based on the standard Fedora 23 template. + + 1. Ensure the existing template is not running. + + [user@dom0 ~]$ qvm-shutdown fedora-23 + + 2. Clone the existing template and start a terminal in the new template. + + [user@dom0 ~]$ qvm-clone fedora-23 fedora-24 + [user@dom0 ~]$ qvm-run -a fedora-24 gnome-terminal + + 2. Attempt the upgrade process in the new template. + + [user@fedora-24 ~]$ sudo dnf clean all + [user@fedora-24 ~]$ sudo dnf --releasever=24 distro-sync + + 3. Shutdown the new TemplateVM via dom0 command line or Qubes VM Manager; + + [user@dom0 ~]$ qvm-shutdown fedora-24 + + If you encounter no errors, proceed to step 7. + + 4. 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 ~]$ qvm-block -A fedora-24 dom0:/var/tmp/template-upgrade-cache.img + + Then reattempt the upgrade process, but this time using the virtual disk as + a cache. + + [user@fedora-24 ~]$ sudo mkfs.ext4 /dev/xvdi + [user@fedora-24 ~]$ sudo mount /dev/xvdi /mnt/removable + [user@fedora-24 ~]$ sudo dnf clean all + [user@fedora-24 ~]$ sudo dnf --releasever=24 --setopt=cachedir=/mnt/removable distro-sync + + (Poweroff via Qubes VM Manager. May need to be killed.) + + 5. `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](/doc/ResizeDiskImage/) before reattempting the upgrade process. + (See **Additional Information** below for other options.) + + 6. After the upgrade process is finished, remove the cache file, if you + created one. + + [user@dom0 ~]$ rm /var/tmp/template-upgrade-cache.img + + 7. Trim the new template (see **Compacting the Upgraded Template** for details + and other options). + + [user@dom0 ~]$ qvm-trim-template fedora-24 + + 8. (Optional) Remove the old default template. + + [user@dom0 ~]$ sudo dnf remove qubes-template-fedora-23 + + +Summary: Upgrading the Minimal Fedora 23 Template to Fedora 24 +-------------------------------------------------------------- + + [user@dom0 ~]$ qvm-clone fedora-23-minimal fedora-24-minimal + [user@dom0 ~]$ qvm-run -a fedora-24-minimal xterm + [user@fedora-24-minimal ~]$ su - + [root@fedora-24-minimal ~]# dnf clean all + [user@fedora-24-minimal ~]# dnf --releasever=24 distro-sync + + (Shut down TemplateVM by any normal means.) + + [user@dom0 ~]$ qvm-trim-template fedora-24-minimal + +(If you encounter insufficient space issues, you may need to use the methods +described for the standard template above.) + + +Differences Between the Standard and Minimal Upgrade Procedures +--------------------------------------------------------------- + +The procedure for upgrading the minimal template (or any template based on the +minimal template) is the same as the procedure for the standard template above, +**with the following exceptions**: + + 1. `gnome-terminal` is not installed by default. Unless you've installed it + (or another terminal emulator), use `xterm`. (Of course, you can also use + `xterm` for the standard template, if you prefer.) + 2. `sudo` is not installed by default. Unless you've installed it, use `su` as + demonstrated above. (Of course, you can also use `su` for the standard + template, if you prefer.) + + +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. + +You can use the `qvm-trim-template` tool: + + [user@dom0 ~]$ qvm-trim-template fedora-24 + + +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](/doc/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. Increase the `root.img` size with `qvm-grow-root`. + 4. Do the upgrade in parts, e.g., by using package groups. (First upgrade + `@core` packages, then the rest.) + 5. 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: + + * [Marek](https://groups.google.com/d/msg/qubes-users/mCXkxlACILQ/dS1jbLRP9n8J) + * [Jason M](https://groups.google.com/d/msg/qubes-users/mCXkxlACILQ/5PxDfI-RKAsJ)
