Ошибка Ubuntu 16.04 при перезапуске apache2

Я пытался перезапустить apache2, и я получил эту ошибку:

root@vps50217:~# service apache2 restart
Job for apache2.service failed because the control process exited with error code. See "systemctl status apache2.service" and "journalctl -xe" for details.
