Oh yeah, I can see how this is going to be a problem. I'll look at changing the code path to use auto-detected compression rather than specific one.
The reason for this change in the first place is that the .tar.gz images will be deprecated in favor for .tar.xz, so I'd recommend JuJu also switch to .tar.xz at some point soon (I don't believe the cloud team has set a timeframe for phasing out tar.gz yet, but it's planned). -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to lxc in Ubuntu. https://bugs.launchpad.net/bugs/1515463 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.
