I manually compiled this for my Pi Zero which is also running Pi-Hole.
I followed 'Enable ipv4 forwarding then reboot to make changes active:' and also got 'net.ipv4.ip_forward = 1'.
I followed the User Management script until sudo wg-quick up wg0.
And from that command, I got the following [#] ip link add wg0 type wireguard [#] wg setconf wg0 /dev/fd/63 Line unrecognized: `PrivateKey=' Configuration parsing error [#] ip link delete dev wg0
Sudo wg has no output.
[#] ip link add wg0 type wireguard [#] wg setconf wg0 /dev/fd/63 Line unrecognized: `PrivateKey=' Configuration parsing error [#] ip link delete dev wg0
Sudo wg has no output.Thanks, Karmanyaah
