This issue has been bothering more of a hundred users for more than a year. In my case there was a workaround at some point, by downgrading openvpn to an older version (can't remember which).
Being so prevailing and old, it is quite disgraceful that this is not being addressed on Ubuntu 16 LTS. Instead, I see some wall of text here (e.g. comment 80) trying to excuse the inexcusable. ** Description changed: [Triage Notes] - This bug can no longer make progress. Please see comment 50 for details - and further instructions. + Apparently fixed on Ubuntu 17.04, nobody caring about LTS versions. + Please see wall of text on comment 50 for a long excuse. [Original 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.
