@wes234234 A simple "apt install ifupdown" will not undo everything that installer has done to setup the system, nor redo it for the alternative networking management tool. Where do you expect ifupdown configs to materialize from? And how do you expect the netplan configs be removed? Given that the system is sensitive to all configs present on disk. This is similar situation to how on the desktop one cannot simply "remove network- manager & install ifupdown" to switch to ifupdown.
"there are plenty of examples" -> can you please give the examples that you have experienced, specifically? the ubuntu developers have gone extensive amount of porting, and integration testing to ensure that as many things as possible are fixed to work, both on new installs and upgrades. I really want to know what is still broken and still needs fixing. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1771236 Title: forced use of systemd-networkd interferes with ifupdown in 18.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ifupdown/+bug/1771236/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
