Thanks - could you please try sudo systemctl stop lxc-net sudo systemctl start lxc-net
then see whether 'ps -ef | grep lxcbr0' shows a result? If it does not, repeat up to two more times (and then just give up and let us know :) If lxcbr0 does show up, does the container (with its original config) come up fine? I've had this issue too - the lxc-net systemd job appears to not be correct, or it interacts badly with network-manager. It doesn't just not show up, it also disappears quite often. ** Changed in: lxc (Ubuntu) Importance: Undecided => Critical -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to lxc in Ubuntu. https://bugs.launchpad.net/bugs/1451232 Title: container does not receive IP address after 15.04 upgrade To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lxc/+bug/1451232/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
