Full Monty is a DVD image. To get it with all applications and configuration, you need to install from the DVD. If you want to keep your current install and have the Full Monty configuration, also, install the fullmonty-lite package via Synaptic and run it. It will create the Full Monty layout and a new user account for it. It will not install the applications for you, though. It is up to you to do that.
