Why is the fix7to8upgrade script sometimes required for plugins?

szymon1051 · Apr 18th 2026

I was upgrading two machines from 7 to 8; omv-extras was installed on them.

On one machine, an error popped up regarding ‘HDD Fan Control’.

The system booted up after a restart, but when I tried to log in via the web GUI, I got a ‘502 – Bad Gateway’ error; even changing the password via SSH using omv-firstaid didn’t help.

I found this on the forum: RE: OMV7 to OMV8 Bad Gateway 502

Code

wget -O - https://github.com/OpenMediaVault-Plugin-Developers/installScript/raw/master/fix7to8upgrade | sudo bash

As far as I can tell, this is from omv-extras.

Why was this required on one machine but not on the other, given that it worked fine on the other one?

I wrote it but it isn't really for omv-extras.

Because the upgrade didn't go perfect. The script is just fixing the common failures.

Now there's a problem with the machine.

I can't install K8s.

the hddfanctrl plugin is having problems. I would remove it and then maybe try reinstalling it. That isn't a plugin I maintain.

szymon1051 · Apr 18th 2026

So K8s installed, but the terminal was throwing up an error about hddfanctrl?

Because I’ve checked and K8s is there.

I reinstalled hddfanctrl and it seems to be working now.

Does hddfanctrl work with OMV 8?

As I said, I don't maintain it or use it but I was told it did work with omv8. That is why it is in the omv8 repo.

Want to try to upgrade my rpi4 4GB (OS on SSD). Will take down all composer containers before, and then...

sudo omv-upgrade

sudo omv-release-upgrade

running the script

Is this the correct order? Do i have to disable flashmemory plugin before?

omv-release-upgrade runs omv-upgrade. so, no reason to do that. Backup before running.

No. The upgrade will automatically move your system to openmediavault-writecache.

KlausR · Sep 2nd 2026

And your script? After or before rebooting, when omv-release-upgrade has finished?

Depends on if something goes wrong. it won't hurt to run but if the upgrade goes well, it isn't needed. post the output of omv-release-upgrade before rebooting if you are worried about it.

KlausR · Sep 2nd 2026

Seems, everything went fine. Thank you.

P.S.: Rpi3B as well, even without running the script

Why is the fix7to8upgrade script sometimes required for plugins?
