[Bug 1518440] [NEW] tgt fails to install in LXD

Public bug reported:

When trying to install tgt in an LXD container the post install script
fails. I've tried setting the container profile as uncontained as per
https://help.ubuntu.com/lts/serverguide/lxc.html#lxc-apparmor to no
avail. This is preventing MAAS from being able to be run in an LXD
container.

** Affects: tgt (Ubuntu)
     Importance: Undecided
         Status: New

** Description changed:

  When trying to install tgt in an LXD container the post install script
  fails. I've tried setting the container profile as uncontained as per
  https://help.ubuntu.com/lts/serverguide/lxc.html#lxc-apparmor to no
  avail. This is preventing MAAS from being able to be run in an LXD
  container.
