Public bug reported: During the do-release-upgrade from 16.04 to 18.04, if the user chooses to preserve the old NetworkManager.conf having "dns=dnsmasq", it does not preserve dnsmasq as the local resolver.
It results in a broken DNS configuration, with /etc/resolv.conf set to 127.0.0.53 but NetworkManager set to dnsmasq. ** Affects: network-manager (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1803236 Title: network-manager: switch from dnsmasq (16.04) to systemd-resolve (18.04) breaks DNS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1803236/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
