title: What does "Desired=Unknown/Install/Remove/Purge/Hold" mean when I enter "dpkg -l" in the command prompt?
body: <p>It appears to be an error. I'm not sure if I should worry about it or not.</p>
  
  <p>FYI: I'm just picking up Ubuntu (10.04) and want to develop a core understanding of how it all works, which is why I'd like to know what this all means. I don't have specific problem that needs solving.</p>
