Reviewing your installation log file it appears that your installation media contains some strange 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 the installation media was prepared. Subsequently, this bug report is Invalid but it would be useful to know what tool you prepared the installation media. Additionally, to resolve the issue you may want to try fully erasing the USB drive which contains the installer before recreating it. Thanks and good luck!
