Update to OMV8 from 7.7.24-4 using omv-release-update failed

MarcLister · Dec 25th 2025

I initiated the update from OMV 7.7 to OMV 8 this morning by using the omv-release-update command in Putty. It took a while but seemed to be progressing OK until I think it was a Python section where it seemed to hang. When I tried to see what was happening it seemed as if it had frozen so I closed the Putty instance and opened a new one. When I re-ran the omv-release-upgrade I got the following error message.

Code

-sh: 1: omv-release-upgrade: not found

If I run the fix7to8upgrade command, sudo wget -O - https://raw.githubusercontent.…ipt/master/fix7to8upgrade | sudo bash", I get this:

Quote

wget: error while loading shared libraries: libnettle.so.8: cannot open shared object file: No such file or directory

Checking for updates in the OMV GUI I get this:

Is my best option to wipe the OS SSD my OMV instance is running on with a Debian image and then install the fresh 8.0.2 ISO for OMV? Or does the 8.0.2 ISO take care of the Debian install for me?

hmoff · Dec 26th 2025

Maybe you just need to run (sudo) ldconfig to fix it?

Otherwise, download the broken library from https://packages.debian.org/trixie/libnettle8t64 and install it.

You probably have that .deb file in /var/cache/apt/archives already.

dpkg -i libnettle8t64_3.10.1-1_amd64.deb

I somehow fixed this last night! Took me a few hours and some hurdles came up as I was fixing things but I got there. I was able to log into the GUI but SMB/CIFS wasn't running despite being enabled. In the early hours I realised that I appeared to have two kernels installed so I removed the older one and that seemed to put me on the right road.

I tried the omv-upgrade and omv-release-upgrade but they didn't solve the issue. I was getting "sub-process /usr/bin/dpkg returned an error code (1)" error messages when I tried to fix anything so I gave methods 1, 2 a go then did a sudo apt update followed by method 4 from this link https://phoenixnap.com/kb/fix-…pkg-returned-error-code-1. That got me a bit further to fixing it. I'd previously tried sudo apt --fix-broken install a few times but kept getting errors.Eventually I was able to omv-upgrade running and then I followed that with omv-release-upgrade and we were getting close. However then the GUI wouldn't let me in and was giving me error 502 bad gateway. I gambled with the fix7to8upgrade script which took a while but once it had done that the GUI let me in, SMB/CIFS was running and the drives were accessible. I did a restart as the GUI recommended it and it's been happy ever since.

My OMV instance is now on running 8.0.2-2 (Synchrony) and the kernel is Linux 6.17.8+deb13-amd64.

I myself have been having some issues with the migration from 7 to 8. The issues / steps Marc listed in his initial post are very close to my own.
I thought all was good, could see the new OMV8 UI. When opening the web GUI I have the yellow changes box appear and asks to apply a range of changes (zfs and so on).

Trying to apply it leads to this error:

Appears to be a little different to Macs output but perhaps has a similar cause?

Looks like another process is updating your system. Wait a few minutes and then post the output of:

sudo omv-salt deploy run apt

Well that process was running for a good hour. Ended with this error code:

Both outputs point to zfs being bonked.
Perhaps I should run apt reinstall zfs?

ryecoaaron · May 11th 2026

The zfs package currently in Debian backports does not compile on the 7.0 kernel in backports. I can't do anything about that. This is one of the main reasons why I recommend using the proxmox kernel.

mihalycsaba · May 11th 2026

from the make.log

Code

checking whether fst->mount() exists... configure: error:
        *** None of the expected "fst->mount()" interfaces were detected.
        *** This may be because your kernel version is newer than what is
        *** supported, or you are using a patched custom kernel with
        *** incompatible modifications.
        ***
        *** ZFS Version: zfs-2.4.1-1~bpo13+1
        *** Compatible Kernels: 4.18 - 6.19

Looks like the latest zfs is only compatible with 4.18 - 6.19 kernels https://github.com/openzfs/zfs/releases

I didn't try to update from omv 7, but I failed to reboot. You have to set the 6.19 kernel as default in grub

You can do this from the omv extras kernel plugin, there's an update grub button, you have to press it, it's not enough if the 6.19 kernel has a checkmark for default for some reason.

mebradhen · May 12th 2026

So I decided to cut my loses and start with a clean upgrade. Before starting the upgrade I made sure to install the proxmox kernel and then reinstall zfs.
Upgrade mostly went smoothly, but failed at the hddfanctrl plugin + 502 error in GUI, but fix7to8upgrade command once again solved that.

But unfortunately no dice, still the got a zfs error. Also applying these pending changes took an hour and a half? Didn't think USB 2.0 would lag it that much. Tbh the entire upgrade process took 6 hours so.

This is the error in question:

Going to now try uninstall ZFS, install the proxmox kernel 6.14 and then reinstall ZFS again.
Might be worth moving to a new thread

ryecoaaron · May 12th 2026

I recommend installing the proxmox kernel, reboot into the proxmox kernel, remove the non-proxmox kernels, and then install the zfs plugin.

mebradhen · May 12th 2026

Will give it a try! Ty for the support!

mebradhen · May 12th 2026

Right I keep running into issue removing the kernels or removing zfs. As zfs is busted I am currently in a loop 22 of OMV trying to build every kernel before doing the action I want.

This fails... as yes zfs is bused. So I'm going around and around.

Granted looking at the code above it appears to have removed kernel 6.12.85 and then tried to rebuild the remainder.

ryecoaaron · May 12th 2026

You need to remove zfs first.

mebradhen · May 12th 2026

Yes I ran apt remove zfs, it did all the same as about and produced this error.

So is there another way to really scrub clean zfs from my system? I kinda assumed it was gone as it's not in the web GUI / plugins anymore. But yeah no 100% I guess.

ryecoaaron · May 12th 2026

sudo apt-get remove zfs-dkms openmediavault-zfs omv-zfs-provider-dkms

mebradhen · May 12th 2026

Had a shot at the above, returns:

I had a typo in my line which I corrected but you cut&paste before I did that evidently. Just remove the word "install".

mebradhen · May 12th 2026

Legend! TY!

With that I was able to complete fixing the kernel issues and get a new install of zfs up and running!

Now running OMV 8 and happy days ahead!

villeneuve · May 12th 2026

Same issue here. How did you, mebradhen , proceed after executing

Code

remove zfs-dkms openmediavault-zfs omv-zfs-provider-dkms

?

*EDIT* I already went ahead anyway & looks like I was successfull. What I did after the above command was omv-upgrade, apt autoclean, apt autoremove, then rebooted and then installed the zfs plugin just via the webinterface which this time worked as it should.

mihalycsaba · May 13th 2026

Just a heads up the next zfs version is in testing, it should be compatible with linux 7 https://tracker.debian.org/pkg/zfs-linux

Update to OMV8 from 7.7.24-4 using omv-release-update failed
