Title:
  Lubuntu 18.04 doesn't boot because dbus-deamon crashes because of
  AppArmor

Status in dbus package in Ubuntu:
  Incomplete

Bug description:
  I experienced this dbus-deamon-cannot-start-because-of-apparmor bug
  right at the first boot after installing (SHA1)
  `048b0b8925f1816b28e3527bfcd47d2842fa9f5e lubuntu-18.04-desktop-
  amd64.iso`. Please note that the installer has downloaded some
  packages files, the bug may not be in a package in the .iso. The bug
  made the first boot unsuccessful, it got stuck indefinitely at the
  boot logo.

  After some debugging in recovery mode root shell, I observed that
  dbus-daemon was a zombie process, restarted by systemd every few
  minutes, and crashing within a second after each restart. I was able
  to get this error message:

    $ journalctl -u dbus -b -f | grep 'Failed to start message bus'
    Failed to start message bus: Error getting AppArmor context of bus: 
Permission denied

  I observed that all systemctl commands were timing out after 60
  seconds, and systemd (strace -p 1) was repeatedly and in vain issuing
  a ppoll(2) system call for reading the dbus socket, and not making any
  progress with its other duties.
