I've noticed today, after upgrading from 24.7.5 to 24.7.6, that NUT on startup is complaining that the UPS is unavailable.
I confirmed the service was running and then from the web UI went to NUT and observed the client was running there according to the settings but it wasn't until I hit the "Apply" button did it start to fully work. I use an SNMP configuration and it seems that during upgrade the ups.conf isn't properly written or something of that nature until I go in an re-apply the settings. They seem to be there from the previous upgrade configuration but I just need to rebuild the ups.conf it seems via the Apply process.
I am more than happy to provide any insight for troubleshooting.
Thanks!
