Got a similar problem with an APC Smartups 450RM serial UPS. As a temporary workaround I added commands in apccontrol to issue the killpower before starting the shutdown. I've had to up the shutdown delay to 3 minutes and up the lowbatt and lowruntime levels to ensure I can shutdown cleanly, but so far, it looks ok.
I'm no expert, so I expect I've missed something... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1634572 Title: APCUPSD does not send killpower command to UPS (only happens on Ubuntu 16.04) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apcupsd/+bug/1634572/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
