I've tried to download DVD images for IA64 using jigdo.There are three of them and the third one provokes an error from jigdo which is along the lines of
"Aaargh --- two files missing. This should not be possible ..." The jigdo target that I'm using is http://cdimage.debian.org/debian-cd/current/ia64/jigdo-dvd/debian-31r3-ia64-binary-3.jigdo I've tried three different mirrors with identical results.
