[Bug 1782785] [NEW] package libapparmor1:amd64 2.11.0-2ubuntu17.1 failed to install/upgrade: package libapparmor1:amd64 is already installed and configured

[Swagman]

Public bug reported:

Borked upgrade from 17:10 to 18:04
I had to go into Recovery Root and enter dpkg --configure -a

On reboot it appears that it's trying to "reverse upgrade"

ie: Bionic to Aardvark
