Yes… The download instructions in general are pretty scattered and confusing.
There are three different methods: upgrade an existing install, fresh install from LiveCD, and fresh install with Ubuntu CD followed by linuxcnc_install.sh. Each of these can be done with several different distros (Lucid and Hardy), and several different LinuxCNC versions, and for sim or realtime. And that's not yet considering the "poweruser/developer" stuff like the buildbot and the git repo, compile-from-source and run-in-place… This information is scattered across a couple of www.linuxcnc.org "Download" pages and several Wiki pages, plus the Getting Started document (in 5 languages!). The instructions could do a much better job describing these methods, how to choose and how to proceed... But I'm not the guy to be the editor-in-chief for this.
