[Bug 1820520] Re: CD ROM failed to read I/O error disk during installing OS

[Sebastien Bacher]

Thank you for your bug report, as you wrote in the bug description it's an I/O error on the disk though, not an Ubuntu bug. From the log
'SQUASHFS error: zlib decompression failed, data probably corrupt'

You should try to check the disk is valid and probably write a new one
