Correct, purging resolvconf is only supported "out of the box"/"just works" in 17.10 and up, as resolvconf/libnss-resolve there have the correct maintainer scripts to do the tansition.
I do not recommend using systemd-resolve in xenial, as it does not have a stub resolver available, and software that does not use nss will not be able to have any network resolution without bypassing resolved. Using systemd-resolved without resolvconf is currently only best supported on 17.10+. ** Changed in: systemd (Ubuntu) Status: New => Confirmed ** Summary changed: - systemd-resolved.service + systemd-resolved.service doesn't play nice if resolvconf is removed on xenial, works on artful+ -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1735296 Title: systemd-resolved.service doesn't play nice if resolvconf is removed on xenial, works on artful+ To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1735296/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
