I am new to the Ubuntu community and the intricacies of openvpn, networkmanager etc but I can confirm this bug on Ubuntu 16.04. I can also confirm the following workarond.
When I disable dnsmasq in NetworkManager, add script-security 2 and up & down stanzas for /etc/openvpn/update-resolv-conf the DNS servers are added to /etc/resolv.conf. But when I stop the foreground openvpn process with ctrl-c the previous pushed DNS servers /etc/resolv.conf are not removed. Ideally /etc/resolv.conf would be restored to the way it was before the openvpn connection. I would like to help out with this but I don't know which system (openvpn, resolvconf, dnsmasq, networkmanager) would or should be responsible for this. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1211110 Title: network manager openvpn dns push data not updating system DNS addresses Status in network-manager package in Ubuntu: Incomplete Status in openvpn package in Ubuntu: Incomplete Bug description: When IPv4 Method is set to Automatic VPN, DNS address recieved from OpenVPN server do not update resolv.conf. This can be achieved when using a standard openvpn config file by adding the lines: script-security 2 up /etc/openvpn/update-resolv-conf down /etc/openvpn/update-resolv-conf In Network-manager there seems to be no option to run connection specific scripts and the DNS data from the server is ignored.
