Thank you for taking the time to report this issue and helping to make Ubuntu better.

This package failure looks like it was caused by bad ISO download, corrupted install media, or device failure. eg. look in the logs and you'll see messages like these :-

Aug 2 07:56:18 ubuntu kernel: [ 774.155608] SQUASHFS error: zlib decompression failed, data probably corrupt
Aug 2 07:56:18 ubuntu kernel: [ 774.155614] SQUASHFS error: squashfs_read_data failed to read block 0x65e6c88

Examining the information you have given us, this does not appear to be a useful bug report so I am closing it, as it appears to be a bad ISO or faulty device (inc. bad write-to-device). If you believe I'm in error, please leave a comment explaining why and change the status back to 'New'. I suggest you verify your ISO download, and note the validation of your ISO before install to ensure a good download & write.
