Ok, somehow the errors are gone (I used) debian host this time but
lxc-attach is still not working... :P
# lxc-attach --name test
lxc-attach: Invalid argument - failed to set namespace 'pid'
lxc-attach: failed to enter the namespace
# lxc-attach --usage
Usage: lxc-attach [-n|--name=NAME] [-h|--help] [--usage] [-q|--quiet]
[-o|--logfile=LOGFILE] [-l|--logpriority=LOGPRIORITY]
