Exactly my problem. This laptop did get with Ubuntu 14.04 lts but with 
tmux 2.0 backported from a PPA, that come with libpam-tmpdir package 
like a recommended dependence. I did removed the libpam-tmpdir package 
in my case, i am the only user in this laptop. I will have this in 
account when we deploy lxc in servers. Weird problem. the problem was 
related with

this can be discused by more lxc developers. Maybe can give problems 
with lxd too. But at least my problem was solved, thanks!
