systemctl не удалось перезапустить ssh

Я пытался перезапустить ssh как

$ systemctl restart ssh
Job for ssh.service failed because the control process exited with error code.
See "systemctl status ssh.service" and "journalctl -xe" for details.

Прочитайте журнал, но не предоставляйте решение. Я должен перезагрузить компьютер.
