linux-libc-dev is already the newest version (6.2.0-23.23).
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
zfs-dracut : Depends: dracut but it is not installable
E: Unable to correct problems, you have held broken packages.
root at Z390-AORUS-PRO-DEST:/mnt/zroot2# ./monta-zroot2
The ZFS modules cannot be auto-loaded.
Try running 'modprobe zfs' as root to manually load them.

# modprobe zfs
modprobe: FATAL: Module zfs not found in directory
/lib/modules/6.2.0-23-generic
