Así que intenté iniciar mi servidor apache2 con el siguiente comando ...
sudo service apache2 start
Pero luego recibo este mensaje de error ...
Job for apache2.service failed. See "systemctl status apache2.service" and "journalctl -xe" for details.
Entonces, cuando trato de ver el systemctl, obtengo esto ...
● apache2.service - LSB: Apache2 web server

http: // localhost / en mi navegador también me da un error que significa que apache no se está ejecutando.
Cuando hago esto ...
sudo restart apache2
Me sale este error ...
restart: Unable to connect to Upstart: Failed to connect to socket /com/ubuntu/upstart: Connection refused
Alguien por favor ayuda.
