[Bug 1868476] Re: Installation crash

[Jean-Baptiste Lallement]

Well, this is strange to have a corrupted media error during
installation while now there is a forced md5 check when the ISO is
booted.

Could you boot the media that exhibits this error, on boot (when the
purple screen with the icon of a keyboard at the bottom) press any key,
then select "check disk for defect". Does is report any error?
