Although Synaptic has a drupal, it's very old!
Preparations
To go with the latest version, I first went with the pre-fork Apache 2, PHP 5 and MySQL 5.
Downloading Drupal
I then downloaded the latest stable drupal version (since I am interested in developing a software engineering platform and personal development environment capable of being moved to a shared hosting environment).

Installing the files for Apache 2
I then copied everything into (in this case) /var/www/drupal-4.7.3, then made the symbolic link (see Drupal Clean URL's on Ubuntu Dapper
