The current kernel version on F34 is 5.12.7 but the kernel header is at 5.12.5. Shouldn’t these two packages be in sync? I have some dkms kernel modules that aren’t building and I think this is the problem.

Kernel headers only get updated when there is a change. That is the current version.

Kernel-headers packages are used for building userspace applications, not for dkms kernel modules. The kernel-devel package is what is used for building kernel-modules, and is always built with new kernels. I typically only rebuild kernel-headers if a stable release has changed the actual uapi head…

Thanks. It turns out that the build failure was caused by a change in a kernel module header; however, I’d swear I saw a warning about kernel-headers when I installed an update.

DKMS will complain about not finding kernel headers. It is somewhat confusing in that drivers need headers from the built kernel to build. Those are in the kernel-devel package, which generally matches the format most things use. libfoo is the library you might use or link against, libfoo-devel is…

This is a way out of date thread and has been necro for over 3 years. If you have a question please open a new thread. Closing this one.
