I had an updates for my Ubuntu server 20.04.3 which is my storage server, with an zfs array. It said that it also was a new kernel (5.15.5-76051505-generic). After the required reboot, the zfs disks are not not mounted. When I try to activate the dkms it says that zfs is not loaded.

Code:
# systemctl status zfs-import-cache
● zfs-import-cache.service - Import ZFS pools by cache file
Loaded: loaded (/lib/systemd/system/zfs-import-cache.service; enabled; vendor preset: enabled)
Active: failed (Result: exit-code) since Wed 2021-12-01 22:21:43 CET; 3min 40s ago

Code:
# /sbin/modprobe zfs
modprobe: FATAL: Module zfs not found in directory /lib/modules/5.15.5-76051505-generic
If I check /lib/modules/5.15.5-76051505-generic/kernel/
There is no zfs modules found.
It seems like kernel 5.15 doesn't come with zfs modules installed?!?!
How do I solve this?
