New Fedora 40 templates are now available for Qubes OS 4.2 in standard, minimal, and Xfce varieties. There are two ways to upgrade a template to a new Fedora release:

• Recommended: Install a fresh template to replace an existing one. This option may be simpler for less experienced users. After you install the new template, redo all desired template modifications and switch everything that was set to the old template to the new template. You may want to write down the modifications you make to your templates so that you remember what to redo on each fresh install. To see a log of package manager actions, open a terminal in the old Fedora template and use the dnf history command.

• Advanced: Perform an in-place upgrade of an existing Fedora template. This option will preserve any modifications you’ve made to the template, but it may be more complicated for less experienced users.

Please note:

• This announcement concerns only Qubes 4.2. Fedora 40 templates will not be available for Qubes 4.1.
• No user action is required regarding the OS version in dom0 (see our note on dom0 and EOL).
