Failure while configuring zfsutils-linux after update to 4.19.0-0.bpo.6-amd64

Hi omv community
I ran into a problem while updating my OMV machine.
It seems like zfsutils-linux and zfs-zed won't update.'

The output from apt -f install :

I am running the normal Debian Kernel (no Proxmox).
Is there a way in which I can easily fix this?
Any help would be greatly appreciated!

Many Thanks

So I got it fixed myself and will leave here what worked for me in case other people run into this issue.
***If this is not wanted by the admins you can remove this thread***

To fix it I unmounted all zfs filesystems using zfs unmount -f [zfsmount] and temporarily removed the mountpoints so the point where the pool should be mounted is completely empty.
After that it was possible for me to run the update using apt -f install. Then you only need to recreate the mountpoints and mount the zfs filesystems. I had some problems with mounting the filesystem afterwards but this was gone after a restart.

Jetzt mitmachen!
