Hello to you all,
recently I encountered a problem when I tried adding a VPN connection via the Network settings.
When I tried adding a "Multi-protocol VPN client (openconnect) the before-mentioned error message is shown.
I already tried to google the problem and I already tried to install “nm-connection-editor”, but this doesn’t solve my problem. “openconnect” is also installed.
My system is up-to-date.
Thank you very much in advance for your help!
