thanks, it doesn’t helped. Now I figured out:

my solution for rpi4 was:

uname -r
apt search linux-headers-$(uname -r)
apt search linux-headers-6.12.47
sudo apt install dkms
sudo dkms autoinstall
sudo apt install linux-headers-6.12.47+rpt-rpi-v8

sudo apt install dkms linux-headers-$(uname -r)
sudo apt install --reinstall zfs-dkms
sudo apt install zfs-dkms zfsutils-linux zfs-zed

At best install the headers meta package instead of the versioned one. Else you need to install new headers on every kernel upgrade manually:

apt install linux-headers-rpi-v8

That one depends on the respective latest versioned one, like linux-image-rpi-v8 does. So whenever the kernel is upgraded, the headers are as well, and DKMS can compile the new ZFS module right away.
