sometimes it occours that a systemd based Linux cannot rebooted.
A roboot is initiated and ends up in an error message: Failed to start reboot.target: Connection timed out
root@devdeb ~# reboot root@devdeb ~# init 6 Failed to start reboot.target: Connection timed out See system logs and 'systemctl status reboot.target' for details. root@devdeb ~# systemctl status reboot.target
I’m not 100% what’s the root cause is, but it seems that a required system service has been terminated or exited.
To intiate an reboot call systemctl with the double –force parameter
root@devdeb ~# systemctl –force –force reboot
