 77

A very simple and straightforward way that worked for me is as follows:

  1. Stop apache2.

    sudo service apache2 stop

  2. Uninstall Apache2 and its dependent packages.

    sudo apt-get purge apache2 apache2-utils apache2.2-bin apache2-common

  3. Use autoremove option to get rid of other dependencies.

    sudo apt-get autoremove

  4. Check whether there are any configuration files that have not been removed.

    whereis apache2

  5. If you get a response as follows apache2: /etc/apache2 remove the directory and existing configuration files.

    sudo rm -rf /etc/apache2
