headers for kernel 5.15.32-v8+ cannot be found #14

Closed rapkin61 closed 2 years ago

rapkin61 commented 2 years ago

sudo dkms install cm4io-fan-0.2.0

Creating symlink /var/lib/dkms/cm4io-fan/0.2.0/source -> /usr/src/cm4io-fan-0.2.0

DKMS: add completed. Error! Your kernel headers for kernel 5.15.32-v8+ cannot be found. Please install the linux-headers-5.15.32-v8+ package, or use the --kernelsourcedir option to tell DKMS where it's located

Don't know if this really is a problem. Kernel 5.15.32-v8+ came via apt upgrade, but kernel headers obviously haven't been updated too;

ah ... got it!

sudo apt install raspberrypi-kernel-headers

did the trick ...

neggles commented 2 years ago

Ah, yep! Interesting, installing dkms should normally bring those in by default... Glad you got it sorted!

Hmmm ... maybe it should, but unfortunately it doesn't. I installed dkms this morning, but that did not update the kernel headers. On the other hand ... installing raspberrypi-kernel-headers triggered the dkms build ...
