Suddenly supervisor broke

After 1 year and half working like a charm today I have started getting this error.
I have home assistant supervised in docker on Debian 9 on a Lenovo mini-pc
All my home assistant work fine with the exception of add-ons installed via supervisor( e.g. node red automations are not fired )

Tried a reboot but did not help. I checked in Portainer and all docker images are correctly working

Any clue ?

Do you have ssh access?

I’m on Debian I have access to terminal

try docker restart hassio-supervisor

I tried to restart it via Portainer.
It restarts but after few seconds it stops

I think this is the error message related

ok then try ha supervisor repair

This what I get

After trouble shooting I found out that apparmor was disabled ( not sure if that could be linked to a short power outage happened yesterday )
I fixed it by

Removing containers
running in terminal the command “export PATH=$PATH:/usr/sbin”
Re-adding containers with the curl command
