    Just for yours and anyone else's information. After uninstalling LAMP with with this command: sudo apt-get remove lamp-server^ MANY things/software were removed. Things that you would think are unrelated... Now when I try to boot, it just hangs at the terminal after rebooting ...[Ok]

sudo apt-get purge mysql-server apache2 php5

That will remove the "big-boy" packages, which should take care of most cases.

You can find this information in the documentation, specifically this section on how to start over:

To remove the LAMP stack remove the following packages:

Note: This assumes you have no other programs that require any of these packages. You might wish to simulate this removal first, and only remove the packages that don't cause removal of something desired.

sudo apt-get remove apache2 apache2-mpm-prefork apache2-utils apache2.2-common libapache2-mod-php5 libapr1 libaprutil1 libdbd-mysql-perl libdbi-perl libmysqlclient15off libnet-daemon-perl libplrpc-perl libpq5 mysql-client-5.0 mysql-common mysql-server mysql-server-5.0 php5-common php5-mysql

To also remove the debconf data, use the purge option when removing. To get rid of any configurations you may have made to apache, manually remove the /etc/apache2 directory once the packages have been removed.

Don't use tasksel to remove packages, bad things can happen, this is covered in this bug report.

The rest of the documentation covers how you would reinstall apache and all the stuff you'll need to get going again.

  • This worked for me: sudo apt-get purge apache2 php5-cli apache2-mpm-prefork apache2-utils apache2.2-common libapache2-mod-php5 libapr1 libaprutil1 libdbd-mysql-perl libdbi-perl libnet-daemon-perl libplrpc-perl libpq5 mysql-client mysql-common mysql-server php5-common php5-mysql phpmyadmin && sudo apt-get autoremove Using: "PHP 5.3.10-1ubuntu3.6 with Suhosin-Patch (cli), Apache/2.2.22 (Ubuntu), mysql Ver 14.14 Distrib 5.5.31, for debian-linux-gnu (x86_64) using readline 6.2"

  • You're assuming that php5 is the only version available

    please note: I ran "sudo apt-get remove lamp-server^" and it removed almost everything on my machine. On the next reboot, I couldn't even get to my desktop.
