Comment 4 for bug 1540159

Reviewing your installation log file it appears that your installation media contains some extra data which is causing the installation to fail. The standard Ubuntu installation media (and that of supported derivatives) does not include this data and will not fail in this way, so it must be an issue with the way your installation media was prepared. Subsequently, this bug report is Invalid. However, to resolve the issue should try fully erasing the USB drive which contains the installer before recreating it. Thanks and good luck!
