Compile Linux Headers for Wireguard

So, I had to create a symlink to build too instead of just source so that wireguard would stop throwing that error while installing (from the message before) .

But now, I got the following:

ERROR (dkms apport): kernel package linux-headers-4.14.69-bpi-r2-main is not supported
Error! Bad return status for module build on kernel: 4.14.69-bpi-r2-main (armv7l)
Consult /var/lib/dkms/wireguard/0.0.20180910/build/make.log for more information.

The contents for that file are attached.wireguard.log (2.6 KB)

Any help is appreciate
