Tycho, I hope I don't botch this thread up too much, I had set emails from this list to digest mode and had to manually copy the content into a new email...
No, I'm not using a custom liblxc build - I have the LXC daily PPA added and am assuming that's where it's pulling from... Not to say I may have dome something crazy in my attempts to troubleshoot. Is there a specific package I can reinstall to ensure I'm getting the appropriate library? alex@osboxesDesktop:~$ apt-cache madison liblxc1 liblxc1 | 2.0.3+master~20160729-2343-0ubuntu1~xenial | http://ppa.launchpad.net/ubuntu-lxc/daily/ubuntu xenial/main amd64 Packages liblxc1 | 2.0.3-0ubuntu3~ubuntu16.04.1~ppa1 | http://ppa.launchpad.net/ubuntu-lxc/lxd-git-master/ubuntu xenial/main amd64 Packages liblxc1 | 2.0.3-0ubuntu3~ubuntu16.04.1~ppa1 | http://ppa.launchpad.net/ubuntu-lxc/stable/ubuntu xenial/main amd64 Packages liblxc1 | 2.0.3-0ubuntu1~ubuntu16.04.1 | http://gb.archive.ubuntu.com/ubuntu xenial-updates/main amd64 Packages liblxc1 | 2.0.0-0ubuntu2 | http://gb.archive.ubuntu.com/ubuntu xenial/main amd64 Packages Hi Alex, On Wed, Aug 03, 2016 at 05:44:56PM -0400, Alex Kedrowitsch wrote: >* Hi All, *> >* I'm new to the Linux container scene and am having issues with making *>* stateful container snapshots.
