I've recently upgraded my Home server form 14.04LTS to 16.04 LTS. ZFS was working fine and the box was succesfuly serving out my samba share and acting as a KODI server and end user (I was succesfully running the SQL database and had multiple nodes around the house).
Perhaps I did it wrong, but after the restart ZFS was no longer up and running and I've had to try to reinstall it. I've tried following all the information that I can online to no avail. Below is the input and output that I get.
All help prethanked.
sudo apt install zfs

Somehow, you have broken dependencies, this is why zfs won't install. Do you still have zfs ppa active? Get rid of them by removing the ppa with the update manager.
With 16.04LTS, zfs is in the standard install.
Use
sudo apt clean, thensudo apt updatefor a fresh start. Do aapt purge zfs*next, but make sure that nothing else besides zfs gets removed!sudo apt-get install zfsutils-linuxis all you need to reinstall zfs. Make sure to import your old pool byzpool import mypoolname, use the -f switch if it wasn't exported before.
