Recently on my Fedora 40 spin with KDE Plasma, as of KDE Plasma 6.1.2 it seems that an update automatically installs the package plasma-nm-sstp, which also installs the following dependencies: NetworkManager-sstp, sstp-client.
After these packages are automatically installed, the ProtonVPN app does not work anymore and I get the following error:

I have yet to confirm that this will happen also on Fedora 40 Workstation Edition, which is with Gnome.
Uninstalling the plasma-nm-sstp packages, which automatically removes the dependencies as well, fixes the problem.

My question is: Can this not be fixed on your side?

I've had issues with this in the past because I had a client that uses this VPN. It's hard for me to see if this is an issue with the package or with the app, but I fear this will affect many other distributions that uses NetworkManager and extensions for SSTP.

Hey @BrotherPatrix

So here's a two part situation. First we don't test on KDE, even though from common knowledge it should work. Second is that it's the plugin that seems to be broken somehow, because all plugins should be loadable (the package does not have python bindings).

there are missing dependencies on the package that are pulled in by proton-vpn-gnome-desktop but not proton-vpn-gtk-app. you can fix this error by installing those dependencies with sudo dnf install python3-proton-keyring-linux python3-proton-keyring-linux-secretservice python3-proton-vpn-killswitch-network-manager python3-proton-vpn-killswitch-network-manager-wireguard python3-proton-vpn-local-agent python3-proton-vpn-network-manager python3-proton-vpn-network-manager-openvpn python3-proton-vpn-network-manager-wireguard

I got the exact same error as OP, which makes me think that this may be the same issue.
