I have seen the same problem and was very disappointed to see that the installer would hang indefinitely while trying to access the network. I found a workaround here:
http://www.ubuntuforums.org/archive/index.php/t-76631.html which I paraphrase here: # Get PID of http process that has hung: $ ps ax | grep http # Kill that process: $ sudo kill <PID of http process> I had to do this several times before the install continued. I had previously tried closing the Installer window like you did and that generated the traceback you reported. The problem was that my computer was unable to access the network. It was still unable to access the network after the installation successfully completed.
