It appears that I cannot set up an OpenConnect VPN connection since Fedora 36. When I try, I get the error message “Error: unable to load VPN connection editor” (see screenshots).
Back on Fedora 35 and before I never experienced that problem.
Looking online, I found an older bug report for Fedora 29, which suggests to install NetworkManager-libreswan concluding the bug.
Other sources (e.g. for Ubuntu) suggest to install openvpn network-manager-openvpn and network-manager-openvpn-gnome.
However, I do have all these packages installed and removed and re-installed them, to make sure that they are not broken.
# dnf list NetworkManager-libreswan NetworkManager-libreswan-gnome NetworkManager-openvpn NetworkManager-openvpn-gnome NetworkManager-vpnc NetworkManager-vpnc-gnome openvpn vpnc

While removed, I even tested to confirm that those VPN options disappeared; and they did. Though once re-installed, I was at square one again.
The installation is a fresh install using Fedora Server 36 which was “uplifted” to Cinnamon Desktop using an installation and configuration script I wrote.
Is there something I missed? A package yet maybe? Some permissions incorrect on specific files? Or did the aforementioned bug return with a vengeance (regression)?
