Errors trying to install Debian 11 (Bullseye) template from testing

User Support
1

Running Qubes 4.0 - I tried installing the Debian 11 template from the qubes-templates-itl-testing repo.

The first time, at the ‘Installing’ step, my machine completely froze (could not even move mouse cursor) - had to hard reset.

The second attempt, once I booted back up, gave me this error:

[miguel@dom0 ~]$ sudo qubes-dom0-update --enablerepo=qubes-templates-itl-testing qubes-template-debian-11

Since then, I get ‘no match for argument qubes-template-debian-11’.

I don’t see any Debian 11 template in my menu.

Anyone have any ideas on what to do from here?

try sudo qubes-dom0-update --action=reinstall qubes-template-debian-11

Thanks - I just tried that, and I got the exact same stack trace above during the (re) installation process.

4

what happen if you try to sudo dnf remove qubes-template-debian-11 then download it again ?

5

I get an error which, despite ‘Complete!’, continues to appear each time I try the command, so I don’t think it’s properly removing the template.

[miguel@dom0 ~]$ sudo dnf remove qubes-template-debian-11

I think the upper ‘root.img’ error indicates an issue extracting it with tar or cat. The problematic code in qvm_template_postprocess.py is on tar xSOf - action against the root.img file (or the cat command that precedes it) which is presumably part of the rpm package that contains the Debian 11 template.

Can anyone provide me a tip on how to obtain this root.img file so I can manually run the tar command against it to see what the underlying issue might be?

OK, I got through it in the end.

I think the original crash I experienced mid-install, is what made things go so wrong for me.

Since I couldn’t cleanly remove the existing package as the template didn’t actually exist as a Qubes template, I cheekily cloned the debian-10 template with a name ‘debian-11’. This allowed a sudo dnf remove qubes-template-debian-11 to finally succeed.

After that, a reinstall worked fine.

Thanks for your help.

Same issue but on a brand new 4.1.1 install.
Similar solution applied.

sudo dnf remove qubes-template-debian-11 did not work either for the same reason that it stated that it did not exist but I could delete the Qube template using Qubes Tools > Qubes Manager (GUI).

Then: sudo qubes-dom0-update qubes-template-debian-11 and it worked.
