title: Ubuntu 11.10 - How do you uninstall Ruby 1.8.7 and install Ruby 1.9.2?
body: <p>Does anyone know how to properly uninstall Ruby 1.8.7 and install Ruby 1.9.2 on Ubuntu 11.10?</p>
  
  <p>I have thoroughly searched and none of the tutorials I've found have worked.</p>
  
  <p>Also, I spent hours... days... months... trying to get RVM to work and it just is a pain to use. Additionally, I will have little use for the older version.</p>
