OpenConnect VPN on Ubuntu 18 set up like the default of OC on Fedora Workstation? Need PA GlobalProtect VPN

As far as I know you cannot setup an GlobalProtect VPN connection inside the GUI. You have to use the terminal to setup the connection, which is actually quite easy:

Open the Terminal by STRG+ALT+T and enter the following command:

openconnect --protocol=gp vpn.url-to-your-server.com

Then the you will be ask all necessary information to setup the connection. Once done, the connection is established.

To safe your time to enter manually the command, create a file on your desktop and name it vpn.sh with the following content:

#!/bin/bash
openconnect -b --protocol=gp vpn.url-to-your-server.com

Safe it. Now you can just click on it, enter the details and to connection will be established automatically.
