Apache2 service won't start in Ubuntu 15.10
I have installed apache2 but it's won't start, when i do
sudo service apache2 start
it's give me this problem
Job for apache2.service failed because the control process exited with error code. See "systemctl status apache2.service" and "journalctl -xe" for details.
so when i enter this command
systemctl status apache2.service
it's give me this message

Answer
It looks like your apache installation has broken... Please try reinstalling apache by running the following commands in the terminal:
sudo apt-get purge apache2
sudo apt-get install apache2
