[Nut-upsuser] Fedora 40 nut-server not starting at boot

[Rick Dicaire]

Hi folks, I'm having an issue with getting nut-server to start at boot on a
freshly installed Fedora 40 desktop. Seems once the machine is up, I can
manually start with systemctl start nut-server and everythings fine.

I've tried with specific LISTEN lines in upsd.conf, also tried without one
specified. Same result, service doesn't start at boot. No apparent errors
reported either:

systemctl status nut-server
○ nut-server.service - Network UPS Tools - power devices information server
     Loaded: loaded (/usr/lib/systemd/system/nut-server.service; enabled;
preset: disabled)
    Drop-In: /usr/lib/systemd/system/service.d
             └─10-timeout-abort.conf
     Active: inactive (dead)

In /usr/lib/systemd/system/nut-server.service there's mention of:

# The `upsd` is a networked service (even if bound to a `localhost`)
# so it requires that the OS has some notion of networking already.
# Extending the unit does not require *this* file to be edited, you
# can instead drop in an additional piece of configuration, e.g. to
# require that NUT data server only starts after external networking
# is configured (usable IP addresses appear in the system) you can
# add a `/etc/systemd/system/nut-server.service.d/network.conf` with:
#   [Unit]
#   Requires=network-online.target
#   After=network-online.target

However adding this file with those three lines (uncommented yes) still
results in no nut-server running, with and without LISTEN lines in
upsd.conf.

Since there's no issues starting the service manually after reboot, I feel
like this is some kind of systemd thing as opposed to a nut config issue.

Various config file contents:

nut.conf

ups.conf
maxretry = 3
[cp1500]
driver = usbhid-ups
port = auto
vendorid = 0764
pollinterval = 5
desc = "toshiba: TV, roku, switch"

Ultimately I need this service to listen on lan interface as I query it
from other lan machine.

Can anyone provide any insight on my issue?

Thanks
