TemplateVM update issue - qubes.SaltLinuxVM

This issue is linked to this 2 year old issue:

My setup (4.1) is based on minimal Debian 11 templates and apt-cacher for updates.

:x: The graphical Qubes Update cannot update any templates. The log points to the qubes.SaltLinuxVM

Updating deb-11-m-signal

Error on updating deb-11-m-signal: Command '['sudo', 'qubesctl', '--skip-dom0',>
  /etc/qubes-rpc/qubes.SaltLinuxVM: line 46: salt-ssh: command not found

:white_check_mark: Open a root terminal and do the manual update: works.
:white_check_mark: Also the the graphical update via the QUbes Manager: works.

Checking the /etc/qubes-rpc/ directory, it misses the qubes.SaltLinuxVM.

I thought this has been fixed

Why do I miss this salt?
Do I need to install it manually for minimal Debian?
