[Nut-upsuser] NUT stopped working after an upgrade

[Bill Gee]

Update - The Fedora 41 upgrade completed successfully.  Nut version is 
now 2.8.2.1.  Nut-scanner still complains about failure to load a 
library.  Everything else is working.  The nut services are running and 
upsc returns valid data from the UPS.
