title: How can I check my BeautifulSoup version and revert it to an older version?
body: <p>I am using beautifulsoup, and I am getting some htmlparser errors with start tags etc.</p>
  
  <p>I read on crummy's site that one suggestion is to go back to an older version (3.08).</p>
  
  <p>I am using Ubuntu, where I did:</p>
  
  <p>sudo apt-get install python-beautifulsoup</p>
  
  <p>to install it.</p>
  
  <ol>
  <li>how can I check what version I have now?</li>
  <li>how can I force a specific version using apt-get? (and how to uninstall what I have now)</li>
  </ol>
  
  <p>thanks (i'm newish to ubuntu)</p>
  
  <p>latest version of ubuntu 10.04</p>
