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.

This seems strange? But after some googling, I found the below alternative
- although I would expect it to work without `/lib/nut/`):
