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 :-

Apr 30 23:55:07 ubuntu kernel: [  442.730115] SQUASHFS error: zlib decompression failed, data probably corrupt
Apr 30 23:55:07 ubuntu kernel: [  442.730123] SQUASHFS error: squashfs_read_data failed to read block 0x2a940f12

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.
