Though the last comment from Alexander wasn't addressed to me, I hoped to apply it, but roaming was not selected, and my wired interface is not listed in /etc/network/interfaces.
I have done some more experiments, but still have no real understanding of the problem. I still can't even understand why this is marked as the parent bug of the duplicate that actually seems to match the problem I'm seeing... However, it doesn't seem to be a widespread problem. (Either that, or the people who have it mostly can't figure out how to get on the network so that they can report it.) -- network-manager should stop managing any interface configured in /etc/network/interfaces https://bugs.launchpad.net/bugs/139403 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
