Thank you for taking the time to report this bug and helping to make Ubuntu better. I noticed that you are installing an older version of Ubuntu, unless you have some specific requirements to run an older release I recommend trying to install the latest LTS version of Ubuntu. We released version 14.04.1, in July of 2014, and it is a Long Term Support release. You can find different ways to obtain it at http://download.ubuntu.com. In the event that you really want to run the older version of Ubuntu please set this bug's status back to New. Thanks!
