No errors reported during agent installation
Steps to reproduce:
Start agent service "$ sudo systemctl start zabbix-agent.service"
Job for zabbix-agent.service failed because the service did not take the steps required by its unit configuration.
See "systemctl status zabbix-agent.service" and "journalctl -xeu zabbix-agent.service" for details.
