New Debian 11 templates are available for both Qubes 4.0 and 4.1.
We provide fresh Debian 11 template packages through the official Qubes repositories, which you can install in dom0 by following the standard installation instructions. Alternatively, we also provide step-by-step instructions for performing an in-place upgrade of an existing Debian template. After upgrading your templates, please remember to switch all qubes that were using the old template to use the new one.
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. For details, please see our note on dom0 and EOL.
Note for 4.1 release candidate testers: Qubes 4.1 release candidates already include the Debian 11 template by default, so no action is required.
