So. My first thread here after using OMV for exactly 30 days, 2 hours and 32 minutes according to the uptime counter. 
I'm having a problem with the Network UPS Tool (openmediavault-nut 2.0) plugin, it threw an error on installation (which I didn't save, silly me...) and now also when I try to uninstall it.
My systemdrive is a USB-drive and the flashmemory (openmediavault-flashmemory 1.9.2) plugin is installed.
Other plugins are:
openmediavault-backup 1.0.11
openmediavault-luksencrytion 2.1.2
openmediavault-snapraid 1.5
openmediavault-autoshutdown 1.0.8
openmediavault-wol 1.0.4
openmediavault-docker-gui 0.2.21
The error shown upon trying to uninstall the nut plugin are:
Error #4000:

I'm a sort of knowledgeable noob, I can work my way around most things but with this I don't even really know where to start... Any and all input is greatly appreciated.
