Hi,
I am not able to setup Wireguard interface on Raspberry pi.

Error:
RTNETLINK answers: Operation not supported


See the stack:
"
pi@raspberrypi:~ $ cd /etc/wireguard/
pi@raspberrypi:/etc/wireguard $ l
-bash: l: command not found
pi@raspberrypi:/etc/wireguard $ ls
publickey  wg0.conf
pi@raspberrypi:/etc/wireguard $ history | grep wg0
   15  history | grep wg0
pi@raspberrypi:/etc/wireguard $ ip link add wg0 type wireguard
RTNETLINK answers: Operation not permitted
pi@raspberrypi:/etc/wireguard $ sudo su
root@raspberrypi:/etc/wireguard# wg-quick up wg0
Warning: `/etc/wireguard/wg0.conf' is world accessible

RTNETLINK answers: Operation not supported
`wg0` is not a valid WireGuard interface
Usage: wg show { <interface> | all | interfaces } [public-key | private-key
| listen-port | fwmark | peers | preshared-keys | endpoints | allowed-ips |
latest-handshakes | transfer | persistent-keepalive | dump]
root@raspberrypi:/etc/wireguard# wg show
root@raspberrypi:/etc/wireguard# wg show all
root@raspberrypi:/etc/wireguard#

"

Any pointers will be appreciated.

Thanks
