Dear Qiyu Yan,

   Thanks; you are correct. I tried a fresh F34 install. The rpm was pulling in kernel-debug-devel not kernel-devel. It then spat:

DKMS: add completed.
Error! echo
Your kernel headers for kernel 5.11.12-300.fc34.x86_64 cannot be found at
/lib/modules/5.11.12-300.fc34.x86_64/build or /lib/modules/5.11.12-300.fc34.x86_64/source.
You can use the --kernelsourcedir option to tell DKMS where it's located.

If I install kernel-devel first it works (well actually it doesn't work but for a quite separate, old, reason which I was hoping F34 might have fixed)

Sounds like an issue with the rpm dependencies. But its also a rather unhelpful error message.

   Dear all,

     I wanted to test openafs on Fedora 34 RC1, using jsbillings
repo, 
relying on dkms.

The problem is the kernel is 5.11.12, but the kernel-headers is
5.11.11.

kernel-headers don't need to exactly match kernel version.

I enabled updates-testing and upgraded, to get kernel is 5.11.15, but
the kernel-headers is 5.11.14!

   So dkms cannot build. I don't seem to be able to find matching
kernel 

I think you may need kernel-devel, just dnf install kernel would be
fine.

& header versions. I can bodge it with a softlink which works, but
this 
may cause others trouble?

       Bill
