The distro is based on Ubuntu xenial. In fact sources.list is the same as my Ubuntu setup. When I try to install ZFS via the normal Ubuntu way (sudo apt install ZFS), there's no zfs.ko.

Can you please help? Thanks

ps. I get the same issue of my laptop (HP 8640p or using virtualbox)

edit:

I just installed the distro on a new virtualbox container. I tried both these ISOs: neon-userltsedition-20171011-0018-amd64.iso and neon-useredition-20171012-1018-amd64.iso.

Here are the steps I followed after the the installation completed (i.e. first boot)

step1: sudo apt update

step2: sudo apt full-upgrade

step3: sudo reboot now

step4: sudo apt install zfs (notice that using zfs package installs zfsutils-linux. Also Ubuntu recommends using zfs package for 16.xx versions: https://wiki.ubuntu.com/ZFS)

Code: 
chiyo@mydesktop1:~$ sudo apt install zfs

step 6: looking for ZFS kernel modules

Code: 
chiyo@mydesktop1:~$ sudo find / -iname "zfs.ko" -type f
chiyo@mydesktop1:~$ sudo find / -iname "spl.ko" -type f
/lib/modules/4.10.0-37-generic/kernel/zfs/spl/spl.ko
chiyo@mydesktop1:~$

step7: getting system info

Code: 
chiyo@mydesktop1:~$ lsb_release -a

There was a problem with zfs in certain kernel versions. Users had to either downgrade or upgrade the kernel to get zfs working. Did you try to do modprobe zfs?

Hi Boonie. I updated my first post with the steps I used + script/system info.

Also on my Ubuntu/Unity 16.04 setup, it's using the same kernel as KDE neon.
 
any particular reason you want zfs? I only ask because out of tree driver, drivers needed to boot the system are a royal PITA
if zfsOnLinux lags behind or the distro lags behind keeping the suite in sync, you will be stuck.

I learnt that lesson in 2001 with Mandrake & ReiserFS ... These days I will only use configurations native to the tree to boot to init. Once init is up sure, external drivers but from bios to init will always be in-tree for me (this also include fakeRAID chips I did that as well.... softwareRAID beats them anyway)
 
It seems that this is a KDE Neon specific problem as other users have had similar trouble with zfs.

someone who got it working said:
Currently, I have installed:

  • spl
  • spl-dkms
  • libnvpair1linux
  • libuutil1linux
  • libzfs2linux
  • libzpool2linux
  • zfs-dkms
  • zfs-doc
  • zfs-zed
  • zfsutils-linux
