Im running Armbian 24.2.1 jammy on odroidm1 with additional zfs volumes.

 

On update, sometimes I had to reinstall the zfs kernel module, but now I have the problem, that the system does not recognize the kernel headers:

I already removed and reinstalled the headers via armbian-config > Headers_remove, Headers_install but without change.

 

apt-get list --installed |grep header

linux-headers-edge-rockchip64/jammy,now 24.2.1 arm64 [installed]

 

do I need to create some magic symlinks or parameters for apt-get to get the headers resolved since the kernel version is missing in the package?

Armbian & Khadas are rewarding contributors

additional info: in armbian-config I see, that the kernel is frozen (I can't remembere to have that configured)

When I select "Defreeze", the dialog just returns and still offers "Defreeze".

 

On a odroidc2 I have similar issue with headers not regognized:

  • In armbian-config of the odroidc2 device the kernel was not frozen so I could update to the latest (6.7.4-edge-meson64)
  • installed headers:
    linux-headers-current-meson64/jammy,now 24.2.1 arm64 [installed]

    but `apt-get --reinstall install zfs-dkms` also returns

Did you reboot after installing headers?

 

I tried on beta software https://paste.armbian.com/ayilamofor and kernel 6.8.7 ... it works https://paste.armbian.com/aqumeheguf.yaml

I think this is a problem .... Odroid M1 was merged into rockchip64 kernel ... remove linux-*-edge-rk3568-odroid and install linux-*-edge-rockchip64 and try again. It must work.

 

Tested also on stable branch https://paste.armbian.com/efilumozaq.yaml

Thanks @Igor for your help,

Did you reboot after installing headers?

yes, I did, but now found out, that installed headers are: /usr/src/linux-headers-6.6.16-current-rockchip64

while kernel still was

Linux odroidm1 6.1.12-rk3568-odroid #23.02.2 SMP PREEMPT Sat Feb 18 00:05:38 UTC 2023 aarch64 aarch64 aarch64 GNU/Linux

I got my Frozen kernel in armbian-config somehow solved by updating firmware and rebooting several times.

Now kernel and headers are in sync again and zfs-module gets loaded!
I will need to reanimate my odroidc2, which I use as a standby for the odroidm1, since that device doesn't boot any more after reinstall latest kernel, but that's another story ...

 

Thanks!
