@MickLesk commented on GitHub (Nov 21, 2024):

Debian 11 dont support python >3.10 in default

Because the installation differs from our standards, I don't see it as an issue.

you need to add this manually.
echo "deb http://deb.debian.org/debian bullseye-backports main" | sudo tee -a /etc/apt/sources.list
sudo apt update
sudo apt install -t bullseye-backports python3.10
sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.9 1
sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.10 2
sudo update-alternatives --config python3

@MickLesk

The standards were changed somewhere along the way, because the requirement was to use Debian 11 (while Proxmox 8 is on Debian 12)

I don’t understand your response. The update script is broken for users who installed LXC using the older script that required Debian 11.

There should be a solution, such as:
1. If Debian 11 is detected, avoid updating and instead provide further guidance for the user.
2. Alternatively, if Debian 11 is detected, include the mentioned fix directly in the update script.

because in the current state it will break older instances and people will come here to report the issue

@havardthom @remz1337 @newzealandpaul what do you say? I don't want to inflate the script. Just because a post is 1 year ago that Debian 11 was used.

Then we should put out an announcement, I have noted the solution above.

@havardthom
tried to follow this https://www.cyberciti.biz/faq/update-upgrade-debian-11-to-debian-12-bookworm/
but I guess I F'd up:

dpkg: error processing package linux-headers-amd64 (--configure):
 dependency problems - leaving unconfigured
Errors were encountered while processing:
 linux-headers-6.1.0-27-amd64
 linux-headers-amd64
E: Sub-process /usr/bin/dpkg returned an error code (1)

It was updated to Debian 12:

root@wireguard:~# lsb_release -a
No LSB modules are available.
Distributor ID:	Debian
Description:	Debian GNU/Linux 12 (bookworm)
Release:	12
Codename:	bookworm

but update is not successful due to the issue above

Maybe introduce a script that updates LXC's to Debian 12?

and then link to this thread:
https://forum.proxmox.com/threads/proxmox-ve-8-0-upgrade-error-while-building-linux-headers-6-1-0-10-amd64.130674/

and then this comment solved the issue:

sudo apt purge linux-headers-* linux-headers-*

update was successful but dashboard did not start, tried manually and got this error:

Continuing with my journey:

  1. Solution was apparently I needed to cd into /etc/wgdashboard/src, looks like an issue with the wgd.sh (and not Proxmox helper) for being that silly
  2. Starting manually worked, but was not able to login, starting in debug showed me this issue:
  File "/etc/wgdashboard/src/venv/lib/python3.11/site-packages/flask/app.py", line 902, in dispatch_request

  1. Found this thread in wgdashboard repo: https://github.com/donaldzou/WGDashboard/issues/509
    if updating before 4.0.x need to remove a field from .ini file, searching the release announcement there was no mention of that breaking change as well

  2. wgdashboard still does not auto start on boot, so needed to update service myself

For any future readers, I think the easiest way to migrate is just to install the new Wireguard LXC and copy over existing wireguard configurations from /etc/wireguard, they should not be affected by the breaking change.
