I had an issue that sounds like this, after disconnecting from an OpenVPN session my DNS would fail, killing dnsmasq and restarting network manager would resolve the problem.
To fix it I removed all network interfaces (lan/wifi/vpn etc) from network manager, rebooted, then re-added the interfaces, the problem appears to have gone away. Hopefully others find this helpful. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1589005 Title: After update DNS work unstable To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1589005/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
