Can't compile ZFS from sources for Ubuntu Lunar

[Mario Marietto]

The uptrace article talks about "zfs-dkms" :

jonathon's PPA

To install the latest ZFS version, add jonathonf's PPA:

sudo add-apt-repository ppa:jonathonf/zfs

And then install ZFS and zfs-dkms to update ZFS Linux kernel modules:

sudo apt install zfsutils-linux zfs-dkms


but I'm on Ubuntu Lunar,the jonathon's PPA does not support Lunar.
