I had the problem with Ubuntu 16.04 out-of-the-box. After a full week of 12 hour days trying to resolve this issue, I was finally about to fix it. I made a longer post about it here.

Step 1: Goto GitHub and clone the following repo to your home folder: https://github.com/masterkorp/openvpn-update-resolv-conf Step 2: Move the .sh files from your cloned rep to the /etc/openvpn folder: sudo chmod +x *.sh && sudo mv *.sh /etc/openvpn Step 3: Run the following command to install new packages for DNS: sudo apt-get install openresolv nscd unbound Step 4: Append the following line to your OpenVPN Client Configuration files (*.ovpn or *.conf). I did this after the configuration directives but before my inline certs (<ca> tag): script-security 2 up "/etc/openvpn/update-resolv-conf.sh /etc/openvpn/update-systemd-network.sh" down "/etc/openvpn/update-resolv-conf.sh /etc/openvpn/update-systemd-network.sh" This should resolve the DNS resolution problem.
