zfs-dkms outdated with Backport Kernel

Hi,

I've installed OMV 4 and also the OMV-Extras for v4. I added the Backport Repo by adding deb http://ftp.debian.org/debian stretch-backports main to my source list. I have installed the 4.12 Kernel and then tried to install openmediavault-zfs but got a error while installing zfs-dkms:

Entpacken von zfs-dkms (0.6.5.9-2~bpo8+1) über (0.6.5.9-2~bpo8+1) ...

It looks like 0.6.5.9 isn't compatible with 4.12 kernel but the spl-dkms package installed just fine. After some testing I noticed, that zfs-dkms has an older version than spl-dkms:

root@OMV-NAS:~# apt-cache policy zfs-dkms
zfs-dkms:
  Installiert:           0.6.5.9-2~bpo8+1
  Installationskandidat: 0.6.5.9-2~bpo8+1

        100 http://httpredir.debian.org/debian jessie-backports/contrib amd64 Packages
        100 /var/lib/dpkg/status

spl-dkms is already on 0.6.5.11 while zfs-dkms is still on the old 0.6.5.9 version.

Is this a bug with the Backports or did I made a mistake?

According to this page (https://packages.debian.org/se…l&suite=stretch-backports) the issue must be on my end since the website shows 0.6.5.11-1~bpo9+1

Okay found the reason... I've forgot to add contrib non-free to my sourcelist since zfs has some weird license.

Yup you're right. /etc/apt/sources.list.d/openmediavault-kernel-backports.list still pointed to Jessie. The Option for the Backport is currently missing in OMV-Extras v4 and also the Website need an update for v4 btw.

What website? omv-extras.org? I updated it a few days ago.

The Guides Page is missing the Download/Setup for v4: http://omv-extras.org/joomla/index.php/guides

I've installed 3.0 first but saw the repo are pointing to the wrong release and found the v4 version just by trying out a different URL

It isn't needed. The code was added to OMV core. If you do omv-mkconf apt, it will fix the sources and pin the kernel so that it shows up in updates.

What should this command do? I've run it and it didn't updated my openmediavault-kernel-backports.list and also didn't updated the source.list

omv-mkconf apt change my backport.list file back to jessie-backports. Looks like there is a bug.

Edit: Not sure why.. lsb_release --short --codename returns stretch (as expected)

root@OMV-NAS:/etc/apt/sources.list.d# rm openmediavault-kernel-backports.list
root@OMV-NAS:/etc/apt/sources.list.d# omv-mkconf apt
root@OMV-NAS:/etc/apt/sources.list.d# cat openmediavault-kernel-backports.list
deb http://httpredir.debian.org/debian jessie-backports main contrib non-free
root@OMV-NAS:/etc/apt/sources.list.d#

Alright thanks!

If you still have time: could you take a look on the jdownloader plugin for v4?
