title: How to upgrade eclipse from Galileo to Helios in Ubuntu 10.10 via "Help->Install New Software..."
body: <p>I know the direct-download method but still want to make the upgrade with the help of Eclipse. When I plan to do so, the following errors rise:</p>

  <p>I am using <a href="http://download.eclipse.org/eclipse/updates/3.6/" rel="nofollow">http://download.eclipse.org/eclipse/updates/3.6/</a> . It seems that I need a newer <code>Equinox Provisioning Publisher</code> to make a successful upgrade. But after a rough search I did not find much information. So what should I do now? Thank you.</p>
