First make sure everything is up to date:

sudo apt-get update

Then you install the stuff that lets PIA use gnome openvpn plugin to pick your openvpn spot easily:

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

Finally you can set things to be automatically managed:

sudo vim /etc/NetworkManager/NetworkManager.conf

changed managed=false to managed=true
