Wireguard: RTNETLINK answers: Operation not supported

Hi, I recently installed dietpi on my oxdroid xu4. When trying to run wireguard, I get this:

panda@OXBACKADROID:~$ sudo systemctl restart wg-quick@wg0
Job for wg-quick@wg0.service failed because the control process exited with error code.

See "systemctl status wg-quick@wg0.service" and "journalctl -xe" for details.

The systemctl proposed gives this:

● wg-quick@wg0.service - WireGuard via wg-quick(8) for wg0
   Loaded: loaded (/lib/systemd/system/wg-quick@.service; enabled; vendor preset: ena
bled)
   Active: failed (Result: exit-code) since Sun 2019-08-25 10:53:56 EEST;

I’m guessing the “RTNETLINK answers: Operation not supported” is the key here, but I have no idea where to start. Any help greatly appreciated.
