Supervisor won't update to 2021.12.2

Was originally on version 2021.10.8 and tried to update to 2021.12.2 last night. Core got updated to 2021.12.2, but the supervisor fails and gives this error in the logs:

ERROR (MainThread) [supervisor.host.apparmor] Can’t load profile hassio-supervisor: Can’t load
profile ‘/usr/share/hassio/apparmor/hassio-supervisor’: exit status 1
ERROR (MainThread) [supervisor.supervisor] Can’t update AppArmor profile!
CRITICAL (MainThread) [supervisor.supervisor] Abort update because of an issue with AppArmor:
Can’t update AppArmor profile!

I am running Home Assistant in a LXC container in Proxmox with a Debian 10 host. Anyone have any ideas what could be going on?

I’ve got the same problem.

I mean it could be related to this?

Debian 10 was depreciated in August.

It definitely could be. I am kind of hoping not, but it was in the back of my mind, part of the reason I made sure to specify I was running on a Debian 10 system ; ) . I’ll hold off for a bit and see if anyone has any other ideas, but will probably end up trying to update to 11.

Do you have OS Agent installed? (and up to date)

It looks like I do have OS Agent installed.
