The ubuntu 14.04 network manager doesn't include openvpn and even after installing that it doesn't include an option to import your ovpn file. Here are the straight forward steps to getting set up.

Install these packages

sudo apt-get install openvpn network-manager-openvpn network-manager-openvpn-gnome network-manager-vpnc

Run this command in a terminal to load the old interface

nm-connection-editor

Then select vpn -> select import -> pick .ovpn file

Oh No: Vpn is blocking regular internet

By default this will block non-vpn networks (e.g. the world wide web); There's an option under "IPv4 Settings" - click the "Routes" button and then check the box next to "Use this connection only for resources on its network" and that will get you back online with the rest of the world.
