The following new templates are now available:

Qube OS 4.1

Qubes OS 4.2-rc1

• Debian 12
• Debian 12 minimal
• Debian 12 Xfce

There are two ways to upgrade your template to a new Debian release:

• Recommended: Install a fresh template to replace the 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. In the old Debian template, see /var/log/dpkg.log and /var/log/apt/history.log for logs of package manager actions.

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

For a complete list of template releases that are supported for your specific Qubes release, see our supported template releases. Please note that no user action is required regarding the OS version in dom0 (see our note on dom0 and EOL).
