Public bug reported: For me on Ubuntu 16.04, `apcupsd` doesn't start when using `sudo systemctl start apcupsd` or `sudo service apcupsd start`.
It didn't appear in `ps aux | grep apc` and I got: % systemctl status apcupsd ● apcupsd.service - LSB: Starts apcupsd daemon Loaded: loaded (/etc/init.d/apcupsd; bad; vendor preset: enabled) Active: active (exited) since Wed 2018-01-10 22:21:00 CET; 34min ago Docs: man:systemd-sysv-generator(8) Tasks: 0 Memory: 0B CPU: 0 Note the `active (exited)` and no processes shown. I suspect that in this case the `systemd-sysv-generator` messed up and cannot correctly start this SysV-Init unit. So basically, the systemd service seems broken in this version of Ubuntu. I fixed it by just installing a proper systemd unit using: curl https://raw.githubusercontent.com/johannbg/systemd-units/4c7ac61a6bf390a4899954f78820d49587b360d7/projects/apcupsd/service/apcupsd.service | sudo tee /etc/systemd/system/apcupsd.service sudo systemctl daemon-reload After that, I can `sudo service apcupsd start` all fine. That service file has contents [Unit] Description=APC UPS Power Control Daemon for Linux [Service] ExecStartPre=-/usr/bin/rm -f /etc/apcupsd/powerfail ExecStart=/usr/sbin/apcupsd -b -f /etc/apcupsd/apcupsd.conf [Install] WantedBy=multi-user.target I don't know if upstream debian has the same problem, but the same fix would work there. ** Affects: apcupsd (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1742558 Title: apcupsd generated systemd unit file doesn't work To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apcupsd/+bug/1742558/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
