I'm having the same problems and I have tested so far with

- PXE Booted Alpine (using 
https://blog.haschek.at/2019/build-your-own-datacenter-with-pxe-and-alpine.html
)
- RasPi 3 and 4 (using 
https://wiki.alpinelinux.org/wiki/Raspberry_Pi#Installation)
- USB booted (using 
https://wiki.alpinelinux.org/wiki/Create_a_Bootable_USB)
- Full disk install on a Server

Only the last method allowed me to install the wireguard packages. I
went to the IRC a few days ago and someone said they're preparing a
method that will allow diskless setups to install these modules but I
didn't get a hold of the guy in charge.

Does anyone have any updates on this matter?
