Well, carp. I'm seeing that same message, too. (macOS 10.14.5) It happens when I run upsmon from launchd, and when the shutdown time arrives.

As a short-term solution, you can start upsmon via sudo, and that should work. (I got upsmon to launch shutdown, but I killed it before it finished.) I have not tried logging out after running sudo.

I will poke around and see what other shutdown methods might work from a launchd context.
