I'm glad to see that I am not the only one fighting this issue on Ubuntu 15.10. This is a real show stopper to this being brought into a production environment. I found the same as post from Tristan on 2015-12-11. I CAN run command line but it is a pain to enter my username/pwd every time I need to launch VPN. There is definitely a bug in how the network manager runs openvpn.

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.
