If you don't have any apache2 configuration that you need, Try to resolve this by removing all apache2 files and configuration and install a new default configuration.

Try the following command to uninstall and remove configuration files.

(You need to stop the apache service before you uninstall):

sudo apt-get purge apache2*

And install it again by typing:

apt-get install apache2
