[Bug 1850243] Re: io error (on dvd)?

[Chris Guiver]

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

Oct 29 02:14:00 ubuntu kernel: [  558.527901] SQUASHFS error: zlib decompression failed, data probably corrupt
Oct 29 02:14:00 ubuntu kernel: [  558.527904] SQUASHFS error: squashfs_read_data failed to read block 0x9ed2274

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 verify your ISO download, and use the 'check disc for
defects' option to validate your media before install to ensure a good
download & write.
