Thank you for taking the time to report this bug and helping to make Ubuntu better. Reviewing your log files attached to this bug report it seems that there is a problem with your installation media (CD/DVD) or with your hardware. Please retry your installation with new media and if it still fails I'd recommend testing your CD drive with other media.
