I'm having exactly the same issue; when I upgraded to Ubuntu 9.10 (from 9.04), I lost all my plugins (Java EE) in eclipse and there are no update sites listed under Install New Software... . When I added http://download.eclipse.org/releases/galileo and selected the Java EE developer plugin, the next button won't do anything, or it will say "an unexpected error occurred"
