NUT is Broken After Udating to 26.1.8_5

[kiekar]

Hello,

I just updated OPNsense to 26.1.8_5 from 26.1.6 and noticed the dashboard widget for NUT shows a message "Nut is not returning a status".

I went to System -> Nut -> Diagnostic and noticed the UPS Status page is empty. I'm currently runing the os-nut plugin version 1.9_1.

Below are the general and backend logs. Any help would be much appreciated.

Thanks

It worked. Thanks

I just got a UPS that has USB output and was setting it up and I have the same blank diagnostic screen and errors in the backend logs.

running the revert and lock didn't seem to fix the errors or cause the diagnostic screen to work.

Instead of a dozen reports for OPNsense I think one to NUT may make a lot more sense:

FreeBSD ports doesn't appear to have any reports or movement on that particular subject.


Cheers,

opnsense-revert -r 26.1.7 nut
pkg lock nut


this fixed my issue as well. THANKS!!! Interesting when trying to figure out why my NUT status was no longer working, Claude informed me that a UI bug has been around since 2021. Not sure if that's related or what but thanks for this temp fix anyway.

FreeBSD ports doesn't appear to have any reports or movement on that particular subject.

It appears in FreeBSD 14.3 & 15.0 installations, NUT version 2.8.4 gets installed.

- FreeBSD freebsd-14a 14.3-RELEASE-p14 FreeBSD 14.3-RELEASE-p14 GENERIC amd64
- FreeBSD freebsd-15a 15.0-RELEASE-p9 FreeBSD 15.0-RELEASE-p9 releng/15.0-n281048-6d536196f1bd GENERIC amd64

I don't think this is a nut issue, but something more specific on the OPNsense pkg. I am running mine in net client mode with a FreeBSD actually connected to the UPS. That FreeBSD server is running NUT installed from a local Poudriere build with version 2.8.5_1. The server is working without issue.
