I just followed the instructions so wireguard was integrated into the kernel. I didn’t touch the script to fetch it.Hmmm.... That's weird as 7 days ago there should be v20200128, or at least v20200121, already released.

Are you sure your Wireguard fetch script is up to date as I'm not sure why it would fetch the archived version other than if your script isn't up to date? Latest should be from 2019121029 (https://git.zx2c4.com/android_kernel_wireguard/commit/?id=c3fb88503cabc2234db2c1dfda41f0288c9f4ba8) and it changed the location to download the module from the archived location to the new one.
Thank you.
Or maybe I'm just very wrong and don't know what I'm talking about. Anyway, thank you very much for this kernel, Freak07.
I’ll check it out when I get a chance

Maybe something has gone wrong or something is missing.
