Apache2 no puede reiniciarse en Ubuntu 16.04

Apache2 no puede reiniciarse en Ubuntu 16.04

Instalé Apache2 en mi máquina Ubuntu. Al principio funcionaba bien ya que comencé y reinicié muchas veces el curso. Pero ahora, de repente, cuando intenté reiniciar me apareció este mensaje de error:

[....] Restarting apache2 (via systemctl): apache2.serviceJob
       for apache2.service failed because the control process exited with error code. 
See "systemctl status apache2.service" and "journalctl -xe" for details.

Cuando lo marqué systemctl status apache2.serviceme dio el siguiente mensaje:

No puedo entender qué podría causar este error.

Como sugiere el mensaje Cannot load /usr/lib/apache2/modules/libphp7.0.so into server, es posible que su mod_php esté roto/faltante/eliminado accidentalmente/etc. Intente ejecutar sudo apt-get install --reinstall libapache2-mod-php7.0para reinstalar el paquete y luego reinicie Apache nuevamente.
