Package: apcupsd Severity: important Version: 3.14.14-0.3 On systems with SNMP or other network configurations, the systemd unit file needs to wait for the network to be available.
Otherwise, apcupsd fails to start at boot, the error is very unhelpful too: apcupsd[828]: snmplite Unable to initialize SNMP systemd[1]: apcupsd.service: Daemon never wrote its PID file. Failing. systemd[1]: Failed to start UPS power management daemon.
