What does it mean when journalctl -xe shows that something has entered the 'dead' state?
Discussion
When you see the message "entered the 'dead' state" in the output of `journalctl -xe`, it means that the service or unit has stopped running and will not be restarted automatically. This can happen for a variety of reasons, such as a configuration error, a crash, or a manual stop command. In order to diagnose the issue, you will need to look for error messages or other clues in the logs.
