Task: Update base template to Debian 13.1 and verify compatibility

[mschabhuettl]

📌 Task summary

Switch helper scripts from Debian 12 to the newly released Debian 13.1 template and test functionality.

📋 Task details

Switch base template to Debian 13.1 and test compatibility

Debian 13.1 LXC template has been officially released by Proxmox:
http://download.proxmox.com/images/system/ → debian-13-standard_13.1-1_amd64.tar.zst

There is already an older issue about Debian 13 (see #7332), but that was for 13.0, not 13.1.

To-Do

• Update base template reference from Debian 12 to Debian 13.1
• Run initial tests with the official 13.1 template
• Verify which scripts/containers are working
• Compare results with Debian 13.0 testing (see Debian 13 UPGRADE Incompatibilities #7332)
• Document remaining incompatibilities

References

Alright, its finally available. I can take a look for the next weeks, i push every ct as single with an special branch

Suggestion: Add Debian version picker

Instead of hard-coding the template, could we add the same selection dialog used elsewhere in the helpers, so users can choose the Debian version (e.g. 12 / 13.0 / 13.1)?

• Default stays on the recommended/latest
• Easier A/B testing between versions
• Consistent UX with existing dialogs

That way we can quickly verify new minor releases without editing scripts each time.

its already so since some months, you need to hit "var_version=13" before the bash call

I mean an interactive selection dialog inside the script itself – so that all available Debian templates from pveam available are listed and the user can simply pick one.

This would make it easier to test different Debian versions (12 / 13.1) without setting variables manually, and keep the UX consistent with the other dialogs already used in the helpers.

No, we removed the whiptails some time ago because many people simply choose the wrong things and mark it as an issue. That leads to even more problems. Either we switch completely to 13, or we stay at 12 (where it is not yet possible). For testing, it's very easy to do via the branch or a variable.

Ok, understood — then I’ll stick with using the variables for now. 👍 Thanks for clarifying!

@MickLesk would it make sense to create (or do we already have) a community-maintained list that documents which LXC helpers are compatible with Debian 13.1?

[MickLesk]

that will be included in the open PR; I just haven't had time to format the list as output/table yet.

I think you mean that compatibility will be listed in the PR once it’s finalized.

What I mean is a simple doc/table where I (and others) can already give feedback when creating/testing 13.1 LXCs before the official release here - so we can report if it works or not and take some workload off you.

Thats an mess of over 300 scripts. Maybe we can push an Site in Discussions or on Frontend. Idk. I Talk later to other contributor
