I got it to run, but what a mess ...
Yes, I am running systemctl daemon-reload and systemctl restart
nut-server after each change I make.
I created /usr/lib/tmpfiles.d/nut-client.conf The owner is root:root
and permissions are 0644. The contents are
# State file (e.g. upsd to driver) and pidfile location for NUT:
D /var/run/nut 0770 root nut - -
X /var/run/nut
I uncommented the STATEPATH line in /etc/ups/upsd.conf.
I created a directory /var/state/ups, set to 777 permissions. Changed
the STATEPATH line in upsd.conf. No success.
I looked at /usr/lib/systemd/system/[email protected] but could not
see any changes to be made. The bug report at RedHat mentions that a
file identified in ExecStartPre does not exist, but I could not duplicate.
I tried running this as root:
NUT_STATEPATH=/var/state/ups NUT_ALTPIDPATH=/var/state/ups
/usr/sbin/usbhid-ups -u nut -g nut -s cyberpower -x port=auto
And it works. I tried it with only one or the other of the two
environment variables, but did not work. It has to have both.

Note that /run is linked as /var/run and the nut user DOES have write
permissions there.
These two statements do not fit together :) Permissions on symlink do
not matter, only the ultimate object's rights do (root-owned /run). The
packaging error is that (/var)/run/nut should have been used for drivers
and upsd, or /var/state/ups as it should also exist and be accessible to
these. For a quick fix you can set
Environment=NUT_ALTPIDPATH=/var/state/ups for their systemd units or
respective custom drop-in files.

Yesterday I upgraded one of my systems from Fedora 36 to Fedora 37.
NUT
was upgraded to version 2.8.0. It no longer runs.
At first I thought it was because of the XFCE Power Manager program.
That program finds the UPS with no problem. I thought maybe the two
programs were competing for the UPS port. I shut down the XFCE power
manager, but that did not help NUT.
Based on the diagnostics given below, I think this is a permissions
problem at /run. The nut user does not have write permissions at /run.
Note that /run is linked as /var/run and the nut user DOES have write
permissions there.
How can I correct this?
