Could it be that this container already had a udev upgrade failure in the past, likely caused by the bind mounts we used to have in /dev?

Running "dpkg --configure -a" and then "apt-get dist-upgrade" will most likely fix your container though (if you didn't do it already).

I'm also subscribing Serge as this might also have been caused by apparmor.

Yes I'm 99.5% certain that this is a dup of the other apparmor bugs
