Ubuntu 16.04: openvpn dns leak

Direct copy from here:
https://bugs.launchpad.net/ubuntu/+source/openvpn/+bug/1211110/comments/58

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:
http://askubuntu.com/questions/829204/dns-routing-fails-for-vpn-connections-on-ubuntu-16-04-out-of-the-box

Here's the abbreviated version.
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 ( 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. Dmitry has the right steps, but I needed the 2nd script for my system to update. Works like my 14.04 system... before I upgraded to 16.04...
