I have to connect to openvpn server. Is there a GUI type client in Zorin to connect to openvpn?
You may try in terminal
sudo apt-get install network-manager-openvpn-gnome
I tested this to ensure it works in my terminal and was very surprised that it returned a message saying that it was already the newest version. I have never installed nor used OpenVPN on my own…
Doing a net search on it mentioned “Pritunl client” (servers) or “pritunl-client-gtk” which may be worth looking into.
