I installed Ubuntu just today to run Wireguard

I then followed their installation instructions for Ubuntu.

$ sudo add-apt-repository ppa:wireguard/wireguard

$ sudo apt-get update

$ sudo apt-get install wireguard-dkms wireguard-tools

Unfortunately their 'Quick start' has been anything but..

$ ip link add dev wg0 type wireguard

RNETLINK answers: Operation not supported 

Freaking STOCK Ubuntu and STOCK Wireguard and i'm getting problems already. This is why I was staying away from Linux in the first place.. yet here I am, posting questions on a troubleshooting forum within hours.

I checked headers, checked updates, etc. No dice.

Just reboot, that should have fixed your problem.

But still: Wireguard although it works fine for me is still in beta and not meant for daily use.
From the developers website at wireguard.com:

Warning: WireGuard is currently under development, and therefore any installation steps here should be considered as experimental. We are rapidly working toward mainline inclusion, at which point we will consider this codebase non-experimental.

Most probably the wireguard kernel module is not loaded.
Just try a modprobe wireguard. If this shows an error, the problem is that the module did not compile correctly for your kernel. This, most probably, is because wireguard is still not completely "stable".

If this is the case, just wait for an update of wireguard, in case of such an error this should be the case within a few days, as the wireguard devs seem to fix these kind of problems very fast.
