How to repair the error 'Failed to load ZFS module stack.'

This shows in total these error lines if you encounter this:

Failed to load ZFS module stack.
Load the module manually by running 'insmod <location>/zfs.ko' as root.

This is most likely to be a dependency issue and I solved it by running this command:

sudo apt-get remove `uname -r` zfs-dkms ubuntu-zfs

Then, without in-between reboot:

sudo apt-get install `uname -r`

And after that:

sudo apt-get install zfs-dkms ubuntu-zfs

Then reboot.
