I just tried the last daily build and the issue is solved. Thanks for the quick help.
FYI: On the earlier versions, lxc complained about not being able to mount proc, but it always continued to run the application anyway so I ignored it. After all, most applications run just fine without proc, plus it makes breaking out of container a bit more challenging. -- 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/1253669 Title: unable to launch lxc application containers when dropping cap_sysadmin To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lxc/+bug/1253669/+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
