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). Please retry your installation with new media and if it still fails I'd recommend testing your CD drive with other media. In the event that is is not in fact an error with your installation media please set the bug's status back to New. Thanks and good luck!
