Well, the string returned by ubuntu-cloudimg-query already requires
mangling to be usable with the lxc-ubuntu-cloud template (as we do
inside the ubuntu-cloud template).

As there are no full cloud images compressed using .tar.xz, ubuntu-
cloudimg-query will continue to return .tar.gz and it's up to whatever
piece of software currently mangles its return value to the .root.tar.gz
equivalent to instead mangle it to .root.tar.xz (as I did in the ubuntu-
cloud template).

Anyway, as I said, I'll be changing the tar commands so they don't care
about the compression algorithm, that should make transitioning much
easier.

Title:
  Broken juju LXC deployments

Status in lxc package in Ubuntu:
  New

Bug description:
  I've just tried using juju to deploy to a container with trusty-
  proposed repo enabled, and I get an error message about 'failed to
  retrieve the template to clone'.  The underlying error appears to be:

    tar --numeric-owner -xpJf /var/cache/lxc/cloud-trusty/ubuntu-14.04-server-cloudimg-amd64-root.tar.gz;
    xz: (stdin): File format not recognized; tar: Child returned status 1; tar:
    Error is not recoverable: exiting now;

  This seems to be fairly obvious, trying to use xz on a tar.gz file is
  never going to work.

  The change appears to be from
  https://github.com/lxc/lxc/commit/27c278a76931bfc4660caa85d1942ca91c86e0bf,
  it assumes everything passed into it will be a .tar.xz file.

  This appears to be a conflict between the template expecting a .tar.xz
  file, and juju providing it a .tar.gz file.  You can see what juju is
  providing from:

    $ ubuntu-cloudimg-query trusty released amd64 --format %{url}
    https://cloud-images.ubuntu.com/server/releases/trusty/release-20151105/ubuntu-14.04-server-cloudimg-amd64.tar.gz

  From the juju deployed host:
  $ apt-cache policy lxc-templates
  lxc-templates:
    Installed: 1.0.8-0ubuntu0.1
    Candidate: 1.0.8-0ubuntu0.1

  From the host running juju:
  $ apt-cache policy juju-core

  All machine involved are running trusty:
