Plex LXC can't be updated - repository no longer has release file

[Ancalgon]

Hy guys,

I need a hand. I have a problem with all my Ubuntu LXC installed via script, PLEX in the first place. The 22.10 verion of ubuntu is not available anymore so I can't update my Plex setup. I have tried to upgrade repositorys and force an upgrade but every time Plex not working anymore. I'm lucky that Proxmox has a backup system.

Do you have any suggestion?
