[Nut-upsuser] NUT stopped working after an upgrade

[Bill Gee]

Running NUT version 2.8.2 on Fedora 40.  NUT installed from the Fedora 
package.  CyberPower CP1000AVRLCD connected by USB.

I updated the system yesterday with all the latest Fedora packages.  Now 
NUT will not run.  Chasing the issue through the layers, I come to this:

================

nut-scanner is correct!  The .so file it is looking for does not exist. 
What the heck happened to it?  Was it ever there?  I have no idea.

Nut-server.service is running, but complains it cannot connect to 
anything.  I also see messages about "Insufficient permissions on 
everything".

Is this - at base - a problem with USB permissions?  Missing .so files? 
Or something else??

Thanks!
