AppArmor Error when upgrading packages

[Jay L]

Hi,

Everything seems to be working fine with Proxmox, but I keep seeing this message on various LXC containers as I perform an apt-get upgrade. Here is the actual message:

Cache read/write disabled: interface file missing. (Kernel needs AppArmor 2.4 compatibility patch.) Warning: unable to find a suitable fs in /proc/mounts, is it mounted?

Is this something that I should be concerned about?

Update: In case it matters, I am running Ubuntu 17.10 Artful.

Thank you,

JL

I just saw this error as well. Installing mysql in an ubuntu 18.04 container

Have either of you gotten any further info on this one?

No, no resolution. However, everything seems to be working fine and so I ignore it.
