How to setup OpenVPN + Fedora(AppVM) for OVPN

This is a great guide, thanks. I have a related question though. I created a fedora-33-minimal template, and applied the same steps to establish a VPN gateway to use it with other VMs. I have installed additional packages as instructed here:

The following list provides an overview of which packages are needed for which purpose. As usual, the required packages are to be installed in the running template with the following command (replace packages with a space-delimited list of packages to be installed)

But the “save” button isn’t active on VPN configuration screen. Is there any package I am missing to install?

Thanks,

Finch
