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

Fri Dec 4 16:12:03 UTC 2015

You have been subscribed to a public bug by Robie Basak (racb):

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.
