Thank you for taking the time to report this bug and helping to make Ubuntu better. We noticed that you were installing the LTS version of Ubuntu using an older version of the installation media. The latest point release of 14.04 is 14.04.5. Please try installing from that version of the installation media and see if that resolves your issue. Thanks in advance!

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. There is an easy way to verify the integrity of the Ubuntu ISO files you download. Could you please visit https://help.ubuntu.com/community/HowToMD5SUM follow the instructions and report back as to whether or not the MD5SUM verified? Thanks in advance.
