Unfortunately my /var/log/dpkg.log is no longer available since I needed to use the system, so I proceeded with wiping it after coming up with an alternative recovery mechanism. Hopefully the log provided by acallan provides the information you need. Dell support actually provided me with a recovery ISO for this specific system (Precision M3800 + Ubuntu 14.04) in case anyone needs it.
