I think this is the issue I have run into as well with a Focal VM. Installing nfs-kernel-server works (although it shows some "Dependency failed" messages) and then the service does not work, it is not an ideal experience having to find an explanation for why online. The linux- image-kvm package provides wireguard-modules and zfs-modules, why does it not work the same way for NFS so that the missing support in linux- image-kvm is detected by apt when installing?
