I have an issue on my VM ubuntu 20.04 where the service elasticsearch failed to start.
here is the result returned after executing the command start service:
# service elasticsearch start
Job for elasticsearch.service failed because the control process exited with error code.
See "systemctl status elasticsearch.service" and "journalctl -xe" for details.
and here is the logs of journal:
