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

|
||||
4. Trim the new template.
|
||||
|
||||
[user@fedora-26 ~]$ sudo fstrim -v /
|
||||
|
||||
5. Shut down the new TemplateVM (from the command-line or Qubes VM Manager).
|
||||
|
||||
[user@dom0 ~]$ qvm-shutdown fedora-26
|
||||
|
||||
6. Remove the cache file, if you created one.
|
||||
|
||||
[user@dom0 ~]$ rm /var/tmp/template-upgrade-cache.img
|
||||
|
||||
7. (Recommended) Switch everything that was set to the old template to the new
|
||||
template, e.g.:
|
||||
|
||||
1. Make the new template the default template:
|
||||
|
||||
R4.0: Menu --> System Tools --> Qubes Global Settings --> Default template
|
||||
|
||||
2. Base AppVMs on the new template. In Qubes Manager, for each VM that is
|
||||
currently based on `fedora-25` that you would like to base on
|
||||
`fedora-26`, enter its VM settings and change the Template selection:
|
||||
|
||||
Qubes 4.0: Menu --> (select a VM) --> VM settings --> Template
|
||||
|
||||
3. Base the [DispVM] template on the new template.
|
||||
|
||||
If you have set the new template as your default template:
|
||||
|
||||
[user@dom0 ~]$ qvm-create-default-dvm --default-template
|
||||
|
||||
Otherwise:
|
||||
|
||||
[user@dom0 ~]$ qvm-create -l red -t fedora-26 fedora-26-dvm
|
||||
[user@dom0 ~]$ qvm-prefs fedora-26-dvm template_for_dispvms True
|
||||
[user@dom0 ~]$ qvm-features fedora-26-dvm appmenus-dispvm 1
|
||||
[user@dom0 ~]$ qubes-prefs default-dispvm fedora-26-dvm
|
||||
|
||||
8. (Optional) Remove the old template. (Make sure to type `fedora-25`, not
|
||||
`fedora-26`.)
|
||||
|
||||
[user@dom0 ~]$ sudo dnf remove qubes-template-fedora-25
