Working nut-driver, working nut-server. That's a lot further than you
were on Tuesday.
It's a little odd that nut-driver worked without STATEPATH being
uncommented in upsd.conf but nut-server needed the change.
@Jim, without digging into source, any reason why that would be the case?
@Bill, you didn't end up doing an 'environ.conf'-style drop-in file at
'/etc/systemd/system/[email protected]/' did you (as that would
explain the difference between the two services)?
You will need to enable nut.target to have things start on boot, and
reboot to make sure everything starts OK.

To: [email protected]
My email client (Thunderbird) does not truncate, but it does wrap.
The truncations come from the way systemctl runs its output through
a pager. When I copy-paste from the bash session, it truncates at
the right edge of the window. I need to use the --full and
--no-pager options to get the full text, which will be wrapped as
needed.
Here is the output from upsd -DD:
===================================

Just for grins, I edited /etc/ups/upsd.conf to uncomment the
STATEPATH line. I set it to /run/nut. When I ran upsd -DD again,
it was still looking at /var/run. However! It successfully
connected to the cyberpower device. Upsc returns good information.

nut-server *should* just work if there is a driver available and running.
OK, run:
systemctl disable nut-server (stop it trying to run automatically)
upsd -DD
And then Ctrl-C to stop it once you have got output to screen with
startup messages.
Then copy back here the output from upsd -DD, preferably without
truncating lines which your mail client seems to do :(
I'm pretty sure that nut-server is using /var/run as its STATEPATH.
Can you also include your upsd.conf, minus commented lines.

Hi Simon -
I modified /usr/lib/tmpfiles.d/nut-client to use /run instead of
/var/run. I checked the startup status of the nut services.
=================
[root@mythtv ~]# systemctl list-unit-files | grep -i nut

nut-driver-enumerator.service enabled disabled
[email protected] indirect disabled
nut-monitor.service disabled disabled
nut-server.service enabled disabled
nut-driver.target disabled disabled
nut.target disabled disabled
==========================
I did a shutdown/reboot on the system. The usbhid driver loaded
without errors and did not complain about /var/run. /run/nut
exists and contains the expected two files.
nut-server also started since it is set to "enabled", but failed
to connect to the driver. It complains about "no such file or
directory". What file is it looking for? I ran journalctl on it
but got nothing more than what systemctl status reports.

Hi Simon -
I ran through the steps you gave below. To quote
Gilbert&Sullivan ... "Modified Rapture!" I suppose I should try
a reboot to make sure everything starts properly.
Not yet with the reboot. Baby steps... :) you have a driver
running from the service file! Celebrations are in order.
Did you need to add the environment drop-in file? At which step
did it work?
But first, there is a problem with upsc. Also nut-server
complains that it cannot connect to the device.
Ok, that's next... your comments are wrong way around :)
nut-server not starting is why upsc doesn't give you anything.
/run/nut exists and contains two files.
Here are some outputs:

Error: Driver not connected
upsc won't work without nut-server running, so this is expected
based on the above failure to start nut-server.
So... next.
Fix nut-client.conf contents, and make sure that you can start /
restart the driver as needed with no errors. Set
[email protected] to enabled for autostart, so with
ONLY the enumerator services and [email protected]
enabled, you should see something like the following for
'systemctl list-unit-files | grep -i nut':
[root@emp80 ups]# systemctl list-unit-files | grep -i nut
nut-driver-enumerator.path
enabled
nut-driver-enumerator.service
enabled
[email protected]
indirect
nut-monitor.service
disabled
nut-server.service
disabled
nut-driver.target
disabled
nut.target
disabled
Stop any running nut processes, and reboot. On reboot the only
thing that should autostart is [email protected]
(from the 'indirect' call via [email protected]). upsc will
still not work.
Monitor the driver for a while 'journalctl -u
[email protected] -f' and make sure it is stable and
stays connected - google searches show some flakiness with some
cyberpower UPSs.
Once you are confident that the driver is reliable, starting OK
and staying up then move on to nut-server.
I'll check in this evening and we can do some more digging on that.

Hi Simon --
Yes, I am pretty sure this is the RedHat packaging problem. I
sure hope they get it squared away. I have only one system
using nut and that is because all my other systems have APC
battery backup and run apcupsd. Apcupsd may be old, grey and
unmaintained, but it Just Works.
You mention that the STATEPATH line in upsd.conf will override
other settings. It does not appear to be the case for me.
The only way I could get the driver to run was by setting
NUT_STATEPATH on the command line. Perhaps that is an issue
with the driver and not nut-server?
In answer to your questions:
1) /usr/lib/systemd/system/[email protected] exists. I have
made no changes to it so far. Here are the contents,
unfortunately line-wrapped by Thunderbird.

===================================
OK, so that's the same as mine. It's ExecStartPre task is to
create the pid folder from your answer to the third (unasked)
question :) which is that outlined in
/usr/lib/tmpfiles.d/nut-client.conf
You have /var/run/nut 0770 root nut - so systemd should ensure
that exists.
By the way, having it with "/var/run/nut" will trigger a
'noise' error about the "/var" path - change it to just be
/run/nut in nut-client.conf.
As a test, what happens if you:
- make sure nut.conf has MODE=standalone
- make sure ALL nut services are stopped, i.e. 'ps -ax | grep
ups' should give you only the grep process as an answer
- delete /run/nut folder (it will get re-created automatically)
- take /etc/ups/upsd.conf back to have commented out STATEPATH
as distributed in the package
- run "systemctl enable nut-driver-enumerator.path
nut-driver-enumerator.service --now" - this will enable and
start the services that monitor ups.conf for changes and then
write the actual driver service file; the second one also runs
early in boot and ensures that the service file exists and is
correct.
- run 'nut-scanner -U' and copy its output into ups.conf
instead of your current definition with name heading
[cyberpower], save and exit: this will trigger the above
enumerators to run and re-do the [email protected]
file
Based on an out of the box install, you have at this point done
enough that the driver should run (*should*!!!!)
- run "journalctl -u [email protected] -f" in one
terminal while you run "systemctl start
[email protected]" in another - what does
journalctl output?
Assuming it does not start (based on what you have said below),
show the messages.
If it still does not start as configured above, but you \can/
run /usr/sbin/usbhid-ups with your environment variables
specified like you had done before, and it *does* run, then do
the following steps to create a systemd drop-in file for the
variable, but make the steps use /run/nut instead of
/var/run/nut:
https://bugzilla.redhat.com/show_bug.cgi?id=2127269#c8
(comment 8, formatted for ease of reading). You want to get
back to the RH/Fedora default of using /run/nut, not
/var/state/ups
1. uncomment the "STATEPATH /var/run/nut" as already mentioned
2. create: /etc/systemd/system/[email protected]/environ.conf
with these two lines:
[Service]
Environment=NUT_STATEPATH=/var/run/nut
3. and finally do: systemctl daemon-reload
...then try and run systemctl start
[email protected] again, while monitoring journalctl.
If that does not work - then I'm out of ideas at this point lol... :-D
'set' has nothing BTW on my working system related to nut.
2) In /etc/ups/upsd.conf, the original STATEPATH line is
STATEPATH /var/run/nut
Right now the original line is commented and I added another
line to point at /var/state/ups.
3) You only asked two questions, but I sense a third might be
important. Originally the system had
/usr/lib/tmpfiles.d/nut-common.conf. I have modified that
file and no longer have the original. I copied that file to
nut-client.conf, and both have the same contents:
=======================
# State file (e.g. upsd to driver) and pidfile location for NUT:
D /var/run/nut 0770 root nut - -
X /var/run/nut
========================
4) And one more unasked question! :-) When I look at the
environment variables on the system, I see this:
========================
[root@mythtv tmpfiles.d]# set | grep -i nut
_=/etc/ups/nut.conf
========================

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.
Hi Bill,
Drivers and upsd share defaults (see 'man nutupsdrv').
Your original error message ("writepid: fopen
/var/run/usbhid-ups-cyberpower.pid: Permission denied") would
seem to indicate, same as the Red Hat bug, that your driver's
default pid path is /var/run.
The driver by default uses STATEPATH (which can be
over-ridden in upsd.conf) to store pid files. The driver
.service file is supposed to make sure that path exists by
running the ExecStartPre line, which gets its instructions
from the referenced ".conf" file from /usr/lib/tmpfiles.d.
The .service file then calls 'upsdrvctl start' to start your
usbhid-ups driver, as defined in ups.conf. Those all need to
align...
2 x questions:
1. Without its comments, what are the active lines (as
installed, without any changes) in
/usr/lib/systemd/system/[email protected] (or wherever that
service file is located on your system)?
2. in your upsd.conf (also as installed, without any
changes), what is the commented out STATEPATH you later
mention uncommenting?
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.
