Hello @Eul'viking welcome to the forum.

Please provide some more info! Which OMV version you are running - you can tag your thread accordingly. What are you doing when the problem occures? Exact error message and so on.

The nut-service would point to the "network - UPS - tools". Did you install an UPS device?

Hello thanks for answering
The problem came after an update/upgrade that went not to the end, i don't know why i might add.

So the solution that i found was to reinstall OMV on the NAS from scratch, it worked.

I have now something that is working fine, i share the folder and can acces from the others computers from the lan.

Now i tiry to connect and configure a scanner/printer with no success... it's an other problem, maybe i should open an other topic

Hey, I've also got this error.
I just installed OMV 4 and want to install the NUT plugin for my UPS.

During the installation I get this error:
