title: Why does Ruby or RVM seem stuck at 1.8.7 on Linux Mint?
body: <p>I am on Linux Mint 12.</p>
  
  <p>I installed RVM and ran these commands:</p>
  
  <pre><code>rvm 1.9.2
  
  rvm --default use 1.9.2
  </code></pre>
  
  <p>but <code>ruby -v</code> still outputs <code>ruby 1.8.7</code>.</p>
  
  <p><code>sudo apt-get install ruby1.9.2</code> returns saying 1.9.1 is the latest version.</p>
  
  <p>How do I get Ruby to be running on 1.9.2?</p>
  
  <p>When I run <code>rvm list</code> like suggested at "<a href="https://stackoverflow.com/questions/5876764/ruby-1-9-2-keeps-reverting-back-to-1-8-7-after-installing-it-using-rvm">Ruby 1.9.2 keeps reverting back to 1.8.7 after installing it using RVM</a>", it outputs:</p>
  
  <pre><code>rvm rubies
  
     ruby-1.8.7-p352 [ x86_64 ]
  =&gt; ruby-1.9.2-p290 [ x86_64 ]
  </code></pre>
  
  <p>So I think I must have a configuration issue.  My OS seems to be defaulting to the wrong version of Ruby.</p>
  
  <p>I ran:</p>
  
  <pre><code>sudo apt-get remove ruby
  </code></pre>
  
  <p>But had no change.</p>
