We are sorry that we do not always have the capacity to review all reported bugs in a timely manner. The following messages can be found in UbiquitySyslog.txt which was automatically attached to this bug report:

Oct 13 20:37:34 ubuntu kernel: [ 282.817783] SQUASHFS error: zlib decompression failed, data probably corrupt

You probably had a bad write to your media and your subsequent write to media was probably a "good" one.

Should you have such a problem in the future 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 it.
