I originally posted this question on StackOverflow. Before it was taken down as off topic, the answer and comments were leading to MPM not being loaded
- I tried
sudo apt-get install apache-mpm-prefork
but was given the error:
E: Unable to locate package apache-mpm-prefork
Below are all the steps I took today which led to the errors I am experiencing:
– Installing phpmyadmin following this tutorial: https://www.digitalocean.com/community/tutorials/how-to-install-and-secure-phpmyadmin-on-ubuntu-16-04
– I got stuck at sudo phpenmod mcrypt
and sudo phpenmod mbstring
as it was giving me some error
– I then tried to diagnose this problem by creating a php file in var/www/html that simply contained <?php phpinfo(); ?>
– It was here that I saw that apache was not serving the php files as the webpage simply outputed <?php phpinfo(); ?>
– So I tried to follow this: https://www.techrepublic.com/article/how-to-fix-apache-2-not-executing-php-files/
– However this restarting was not working so I performed sudo service apache2 stop
in hope that I could start again
– sudo service apache2 start
gives the error:
Job for apache2.service failed. See 'systemctl status apache2.service' and 'journalctl -xn' for details.
-
Okay so
sudo systemctl status apache2.service
i guess:- apache2.service – LSB: Apache2 web server

I tried deleting what I changed in the config file but it still outputs the same
ANY help would be greatly appreciated; I really do not want to have to reinstall apache. Thanks.

welcome to serverfault!
As of Ubuntu 16.04 server the mpm-prefork module is included in the package apache2-bin. In order to install it you have to enter
After that you will have to enable the mpm_prefork module like this:
and then try again to start apache2:
The detailed error log is located here:
journalctl and systemctl only give very basic information.
If you should furthermore have problems with installing the php modules mcrypt and mbstring then please post the complete error messages you get.
Hope this helps!
