Wait, that's the wrong folder; my bad!

Try ls -l /lib/modules/6.2.10-arch1-1/build/include/ and ls -l /lib/modules/6.2.10-arch1-1/build/include/generated/.

There you go:

[valadaptive]

That's really bizarre. generated/autoconf.h should be present in the linux-headers package, but it isn't there. Try reinstalling linux-headers?

Did you install uwurandom-git-dkms from the AUR? Try removing it.

[orhun]

That fixed it, thanks! I guess having the AUR package installed and trying to compile manually didn't work.

I'm wondering why though. Is there an explanation?

[valadaptive]

Looks to be the same thing that happened to another DKMS package-- a typo in dkms.conf. I don't own the uwurandom-git-dkms package, so I can't fix it myself. @bs2kbs2k Mind fixing it?

[bs2kbs2k]

I'll do that soon Apr 15, 2023 10:47:36 AM valadaptive ***@***.***>:
