apparmor issue

[AxelTwin]

Hi everybody,

I hava a weird issue on one of my container. I upgraded it to ubuntu 20.04LTs a few days ago, everything was fine. Last night I rebooted the prowmow and this morning the container wont run properly. Here is what I get from syslog:

May 20 08:39:02 srvdc kernel: [  707.472536] audit: type=1400 audit(1589956742.676:120): apparmor="DENIED" operation="mount" info="failed flags match" error=-13 profile="lxc-125_</var/lib/lxc>" name="/run/systemd/unit-root/" pid=27191 comm="(ionclean)" srcname="/" flags="rw, rbind"

Any idea ?

hi,

this error doesn't tell much.

this morning the container wont run properly

what do you mean exactly? it doesn't boot?

you can try getting debug logs[0] and posting them here, along with the container config (pct config)

Thanks for your reply,
I can't answer anymore, I had to restore the container from snapshot to allow customers to work.
This happend on 2 containers running ubuntu 20.04LTS, samba DC and nextcloud after I updated and rebooted proxmox.
The containers were able to start but Samba AD DC was broken, PHP 7.4.6 as well....
Not sure exactly what happend

The containers were able to start but Samba AD DC was broken, PHP 7.4.6 as well....

maybe it just had something to do with the ubuntu upgrade. (since the containers were able to start)

what was the previous version of ubuntu on the container?

possibly during the upgrade configuration files were touched/modified/deleted...
