Pi 5 - can't build ZFS module due to kernel headers

[Hank Barta]

Good evening,

Armbian noob here (Debian veteran) working with an RPi 5. I've just installed `Armbian_24.2.5_Rpi5b_bookworm_current_6.6.23.img.xz` and would like to build the ZFS modules. I've installed the kernel modules using `armbian-config` but when I try to build I get

 

 

root@meson:~# dpkg-reconfigure zfs-dkms
Deleting module zfs-2.2.3 completely from the DKMS tree.
Loading new zfs-2.2.3 DKMS files...
Building for 6.6.23-current-bcm2712
Module build for kernel 6.6.23-current-bcm2712 was skipped since the
kernel headers for this kernel do not seem to be installed.

Edit: Current situation:

 

root@meson:~# dpkg -l linux-headers-current-bcm2712 linux-image-current-bcm2712

It seems that the headers for this kernel are not available. `armbian-config` lists only a newer kernel as an option (6.7) `apt search` lists older kernels, probably from the Debian repos. Can I switch to these or is there something else I can do?

 

Thanks!

Switch to nightly kernels (those are becoming stable in two weeks anyway), update, reboot. Remove / Add kernels and it will work. Use armbian-config -> software to make this easy way.

Welcome!!!

Thanks for the suggestion. There was no option for kernels in armbian-config -> software. I there was an option to switch to nightly in armbian-config -> system and I executed that. It installed a new kernel and now the system hangs on the 4 pixel rainbow screen.

 

I should probably have mentioned that this is on a Pi CM4 booting from an NVME SSD. I'm trying things out on that to avoid swapping NVME SSDs on my Pi 5. I'm aware that RpiOS runs different kernels on Pi 4 vs. Pi 4B/CM4 but they install both and choose the correct one during boot.
