To me, the issue has presented itself only after dist upgrade from xenial to bionic. While still on xenial I did not observe this problem.
At the same time I can confirm that I receive an email with the contents: "Communications with UPS 1 lost" but no email containing: "Communication with UPS 1 restored" -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1576957 Title: apcupsd alerts on every boot: Communications with UPS lost To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apcupsd/+bug/1576957/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
