Can you please transfer this to the ifupdown package? Or should I just resubmit it from scratch? The discussions of the importance of ifconfig are beside the point. The problem presented itself during boot-up, in connection with an "auto dummy0" directive in /etc/network/interfaces.
If "auto dummy0" and "ifup dummy0" are not maintained then why bother to have a dummy device at all? This is the most important context, although there are MANY others. I reported the ifconfig context because it is the /simplest/ ... not the only manifestation. And no, I'm definitely not the first person to encounter the bug. I'm just the first to report it through this channel. My first message in this thread linked to a report that came up in another context. As for the software versions: I must have typed the "apt-cache policy net-tools" in the wrong window at one point. As stated before that and after that, the fact is that bionic is buggy while xenial is not. Specifically, the buggy packages are: :; apt-cache policy net-tools net-tools: Installed: 1.60+git20161116.90da8a0-1ubuntu1 Candidate: 1.60+git20161116.90da8a0-1ubuntu1 Version table: *** 1.60+git20161116.90da8a0-1ubuntu1 500 500 http://us.archive.ubuntu.com/ubuntu bionic/main amd64 Packages 100 /var/lib/dpkg/status and perhaps more to the point: :; apt-cache policy ifupdown ifupdown: Installed: 0.8.17ubuntu1.1 Candidate: 0.8.17ubuntu1.1 Version table: *** 0.8.17ubuntu1.1 500 500 http://us.archive.ubuntu.com/ubuntu bionic-updates/main amd64 Packages 100 /var/lib/dpkg/status 0.8.17ubuntu1 500 500 http://us.archive.ubuntu.com/ubuntu bionic/main amd64 Packages -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1828749 Title: ifconfig dummy0 : Device not found To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/net-tools/+bug/1828749/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
