Ubuntu Satanic Edition is a Linux distro themed around Satanism, which contains plenty of open-source software and metal music. As its name implies, it's based on Ubuntu. Despite starting out as a theme pack for regular Ubuntu as well as Kubuntu, it eventually became its own OS. The distro's slogan is "Linux For The Damned"

Trivia:
- Nowadays, the distro's domain (ubuntusatanic.org) just redirects to a barebones tip website for Ubuntu users
- Ironically, the skinpack can also be installed on Ubuntu Christian Edition
