Hi, it comes to me that you could try
http://us.cdimage.debian.org/cdimage/snapshot/Debian/ as answer to jigdo-lite's request for "Debian mirror" (while being in the directory with the .jigdo file and the incompletely filled .iso). Maybe this brings you the missing 62 files. (It would also bring up the question why that mirror does not work as fallback for other less well filled mirrors.) Have a nice day :) Thomas
