Friday time is the candy time. Here it goes:
Install the correct repository key
sudo apt-key adv –keyserver keyserver.ubuntu.com –recv-keys 0AAFAD78
Add the repository source to sources.list
sudo vi /etc/apt/sources.list
And add the following sentence
deb http://ppa.launchpad.net/merlwiz79/nimbus/ubuntu jaunty main
Update the repositories
sudo apt-get update
Install the Nimbus theme
sudo apt-get install gtk2-engines-nimbus nimbus-icon-theme

UPDATE: 2010/01/22: Nimbus theme has troubles with MonoDevelop. Since „Nimbus“ is not officially part of Ubuntu, quick fix is change of theme „Controls“ to something else, for example „ClearLook“.
Download: easy_e17.sh
Installation hints: Run the script with `/bin/bash easy_e17.sh -i`.
