I examined the differences between bionic and upstream NetworkManager source around systemd-resolved interactions. I did not see any significant differences to blame for this.
I have just tested it on a build from nm-1-10 branch of upstream NetworkManager and the behavior seems to be identical: the DNS for VPN is lost. This looks like an upstream issue. I will do more testing to confirm. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1851793 Title: NetworkManager OpenVPN No longer sets up DNS if "Use this connection only for resources on its network" is ticked To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager-openvpn/+bug/1851793/+subscriptions -- ubuntu-bugs mailing list email@example.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
