Comment 21 for bug 1634572

I have been fighting this problem for quite a while. It is gratifying that others also have the same problem. I have tried using several linux releases, including Debian, Fedora, Ubuntu, and Mint. All have the same problem, ie, the UPS will not power down after the system is shut down. My experience is that killpower is not shutting down the UPS.

I have had the problem with an APC back-ups 350 with a USB cable, an APC smartups 1400 with a serial interface to a USB port, and an APC smartups 620 with the same serial inteface to a usb port. Apcuspd v3.14.14.0, V3.14.12.0, and all of these with Fedora 25, Mint Mate 18.0, The latest release of Raspbian on a Raspberry PI, and Ubuntu mate on a Raspberry PI. The system shuts down as expected, but I cannot get the UPS to shutdown after the system shutdown. HELP!!!
