[Bug 1518440] Re: tgt fails to install in LXD

Mon Dec 21 19:45:45 UTC 2015

Thanks Ryan for patch from upstream and testing though -- gave better
confidence for updating to latest upstream version.

Please test new version when it lands too, to make sure that I and/or
upstream didn't mess anything up.

Title:
  tgt fails to install in LXD

Status in MAAS:
  Triaged
Status in tgt:
  New
Status in tgt package in Ubuntu:
  Triaged

Bug description:
  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.
