- use latest minor version if you need 14.04 (e.g. 14.04.4, and run apt-get
update && apt-get upgrade afterwards)
- uninstall any remains of cgmanager (libcgmanager0 is fine though, don't
uninstall it) or libpam-systemd
- use https://launchpad.net/~ubuntu-lxc/+archive/ubuntu/lxc-stable ,
It IS possible to run unpriv containers with lxc-1.x, but in my experience
it requires some intervention here and there (like "chmod" or "setfacl").
On the other hand, lxc-2.x from ppa simply works.
