Ubuntu 20 disaster after update

Yes, this morning I was in the mood of updating everything on my ubuntu 20.04 server and reboot.
Now my watchguard and storagenodes stopped working with this message:

Error response from daemon: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: error during container init: unable to apply apparmor profile: apparmor failed to apply profile: write /proc/self/attr/apparmor/exec: no such file or directory: unknown
Error: failed to start containers:

Do you have an idea how to fix this?

Ok, I fixed installing apparmor and restarting docker.
Couple of minutes of terror… nothing else :slight_smile:
