"Error: unable to load VPN connection editor" shown when ttrying to add VPN connection
When trying to create a fortisslvpn connection through the Gnome Settings, you see the "Error: unable to load VPN connection editor".
Creating the same connection via nm-connection-editor
ui is fine, and then all is working(!) (though you will never be able to see/edit the settings in the Control Center).
When starting the gnome-control-center
via cli in terminal I get the following errors:
$ gnome-control-center
