Trust you are dealing with a nontechnical user who needs elaborate specific instructions known to work.
I have had no luck using the network manager with credentials from either platform. It seems to require certificates for connecting which neither furnishes. If I use the OVENVPN option for password only, and enter the node, username and password the save option stays grayed out.
Thanks in advance for any clues or breadcrumbs through the forest.
Has anyone had success installing either nordvpn or protonvpn in late 2023?
Protonvpn-gui and protonvpn-cli are in the repo
I installed ProtonVPN from the Software Center to do a little testing. The GUI is pretty easy to use. I'd recommend trying it.
