I have backported the fix to trusty in my ppa. Unfortunately I was not able to reproduce this issue (although my tests are ongoing). With that being said I would really appreciate anyone that is affected by this issue to give it a try and let me know whether the backport fixed that for them.
The ppa with the backport is ppa:dgadomski/lp1375821 Thank you! -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to mailman in Ubuntu. https://bugs.launchpad.net/bugs/1375821 Title: ifupdown doesn't bring loopback to state up To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ifupdown/+bug/1375821/+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
