This looks a bit like a hardware (or kernel driver) issue, the problem happens much earlier than where the system appears to stop, you're just getting that because the install fails in general, so it throws you back to the main menu.
You got dpkg-divert failing to be found, apt-get failing, etc.: http://paste.ubuntu.com/26127207/
And in general, sprinkled here and there on the log, there are usercopy / scsi subsystem kernel errors: http://paste.ubuntu.com/26127212/
