Hi all, Yesterday, I bought a UPS for the first time in my life, and was eager to dive into NUT. But not all is working as expected... I saw a similar thread started on 18 October, but it didn't help me. (I also spent a handful of hours searching the web for solutions, and of course read the manual and FAQ - "queequeg".)
I tried shutting my UPS (APC "Back-UPS BX750MI FW:295202G -302202G") down with `sudo upsdrvctl shutdown`, but no response. Digging around, I found a few things that raised my suspicion, but I can't figure it out... I followed this fine gentleman's guide (but tweaked it a bit - I don't know why he uses `master` and `slave` for example?): https://www.youtube.com/watch?v=vyBP7wpN72c. I must add that I created a few users and user groups during installation and configuration, following the documentation. But in the end, I lost oversight, and everything didn't work. So it's entirely possible there's a permissions issue somewhere. But I don't have any idea where... Because of the trial-and-error approach, in the `.conf` files (shown below), a lot of stuff is commented out. I assume I can delete it, but I also assume the `#` should be adequate? Anyway, I keep it in the output below for clarity. I'll just paste various outputs here, I hope that's a reasonable approach? Thanks in advance for anyone's help! Kind regards, Erik PS. I also created a GitHub issue ( https://github.com/networkupstools/nut/issues/2666). Maybe doing that AND mailing this, is not the correct procedure? In that case, I apologize. ``` erik@MinipcLG2:/$ sudo upsdrvctl shutdown apcupskelder Network UPS Tools - UPS driver controller 2.8.1 Network UPS Tools - Generic HID driver 0.52 (2.8.1) USB communication driver (libusb 1.0) 0.46 select with socket: Invalid argument Can't claim USB device [051d:0002]@0/0: Entity not found upsnotify: failed to notify about state 4: no notification tech defined, will not spam more about it Driver failed to start (exit status=1) ``` ``` erik@MinipcLG2:/$ sudo nut-scanner -U Scanning USB bus.
