Thank you for taking the time to report this bug and helping to make Ubuntu better. While we appreciate the difficulties you are facing, it would appear that the image (ISO file) you downloaded could be corrupt or you had a bad write to installation media. From the description:

> CasperMD5CheckResult: fail

Re-downloading the ISO file and re-writing it to your installation media is a way to troubleshoot this issue. Since the issue is not a bug, this report will be closed.
