Please make sure your system is fully up-to-date. Especially make sure your systemd package is 237-3ubuntu10.22 or newer. Now check your network-manager package. If it is not 1.10.14-0ubuntu2 (probably it is 1.10.6) update it from bionic-proposed as described in comment #11 of bug #1754671. Then reboot. Now check whether the problem does not occur any more for you, for example by doing the steps of the section "[Test case]" in the description of bug #1754671.
If the problem still persists, follow the instructions of my comment #9. Also post the output of systemd-resolve --status here. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1829838 Title: 1.10.14-0ubuntu2 breaks DNS propagation from VPN To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1829838/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
