One more information that could hopefully help the investigation. I have 3 network interfaces (em1, p1p1 and p1p2) but today I only use one (p1p2) the 2 others do not even have a cable plugged in.
So only p1p2 is configured to be up with a DHCP configuration and some firewall rules. And guess what, only p1p2 is "renamed" the 2 other unused interfaces are *never* renamed!?! Maybe that help tracking down the problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1284043 Title: udev renaming the same hardware network i/f to different name, breaks networking and firewall To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1284043/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
