[Bug 1870792] Re: ubiquity Install stops with i/o error

[Jean-Baptiste Lallement]

Thanks for your report.

The installation media is corrupted
Apr  4 14:18:53 ubuntu kernel: [  642.829814] SQUASHFS error: zlib decompression failed, data probably corrupt
Apr  4 14:18:53 ubuntu kernel: [  642.829814] SQUASHFS error: squashfs_read_data failed to read block 0x37545

The system performs an integrity check on boot of the ISO. Did you see
any error message when you booted the ISO?
