Yeah but there’s still that Slim Application Error in the logs…
In this particular case, I think it doesn’t matter whether you’re using Debian 12 or 13, or an LXC or a VM, except that the problem apparently manifests itself differently, or perhaps there were additional problems in the LXC. However, none of this changes the fact that AIO 11.11.0 is not compatible with the latest Docker version.
So either downgarde Docker to the previous version and put the packages on hold as I described here: AIO NC does no longer start: Slim Application Error - #14 by bb77
Alternatively, you could install the AIO 12.0.0 beta. However, I’m not sure whether everything, especially Full Text Search and ClamAV, is already running smoothly in that version.
If you want to be on the safe side, downgrade Docker and then set the Docker packages on hold using apt-mark hold until AIO 12.0.0 is officially released. Once it’s available, upgrade AIO, then apt-mark unhold the packages and update Docker.
