A quick look says both ppa are using 2.0.1, so you should have identical result.

My GUESS is that your user cgroups (via libpam-cgfs) was not properly
setup. A logout-login (as that normal, non-root user) would probably
do the trick. Note that last time I check su and sudo (to the user)
will not work.

Another alternative going forward, is to run your containers as root,
but use "lxc.id_map" in /etc/lxc/default.conf, so that new containers
would be unprivileged, root-owned containers. Or use lxd, which does
similar thing by default.
