After making one modification the install was a complete success. Originally I was trying to have /dev/sda5 be my root partition and /dev/sda6 be my /home partition. The home partition contained my user folder from my 8.04.1 installation. I wondered if this was causing the error, so I simply told ubuntu to use /dev/sda5 for root without specifying any other partitions to have any other function (so everything is on that partition) and the install went fine.
