The following errors can be found in UbiquitySyslog.txt which was automatically attached to this bug report:

Oct 6 07:26:13 ubuntu kernel: [ 679.743816] SQUASHFS error: zlib decompression failed, data probably corrupt

It's possible you have a bad write to your media. If you're still having problems please try the option to check the integrity of the image from the installer boot menu, and if this confirms that the media is corrupt, try re-writing and/or re-downloading it.
