@Stephen: I had the same problem after today's upgrade. Activating the proposed repository and upgrading lxc to version 1.0.7-0ubuntu0.9 fixed the issue for me.
See comment #11 for details. But it's a shame this proposed fix was not released to everyone before the new kernel. ** Tags removed: verification-needed ** Tags added: verification-done -- 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/1504781 Title: lxc-test-ubuntu hangs forever in trusty-proposed with Linux 3.13.0-66: AppArmor denies /dev/ptmx mounting To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1504781/+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
