Comment 2 for bug 1836284

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 a corrupted file system, or device failure. eg. look in the logs and you'll see messages like these :-

Jul 12 01:31:22 ubuntu kernel: [ 201.764811] SQUASHFS error: zlib decompression failed, data probably corrupt
Jul 12 01:31:22 ubuntu kernel: [ 201.764815] SQUASHFS error: squashfs_read_data failed to read block 0xe81c6e3

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 faulty device (or 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 use the 'check disc for defects' option to validate your media before install to ensure a good download & write.
