Interestingly the command does work, it only crashes on exit:

I guess that's about https://github.com/opnsense/ports/commit/ffa95e659d223da -- we had 2.8.3 in our tree before which would still work?

# opnsense-revert -r 26.1.7 nut

Ok not sure what to do here, but I'll see if there is an upstream patch. Rolling back the version is iffy.

Did a quick trace of 2.8.5 and it appears to use /proc, whereas 2.8.3 doesn't. I don't know if this has anything to do with it.

I am seeing the same behavior since upgrading to 26.1.8.

I also appreciated the technical debt comment. Thanks for the laugh.

Sure, it was that type of response too good not to share.  :)

Per the release notes there was no change to the nut package.  So what are you all even talking about? :P

With 2.8.5 the NUT widget reports an error.

Listed are the tail ends of ktrace for upsc in 2.8.3 & 2.8.5.
