Once you have a working network-manager (in regards to this bug), you can prevent that version from being upgraded (until you verify the bug is fixed) like this:
sudo apt-mark hold network-manager To prove this is working you can run: sudo apt-get upgrade -V Then you'll see this: The following packages have been kept back: network-manager (1.1.93-0ubuntu4 => 1.2.2-0ubuntu0.16.04.3) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1633874 Title: VPN - "Additional DNS servers" Settings are being Ignored To manage notifications about this bug go to: https://bugs.launchpad.net/network-manager-applet/+bug/1633874/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
