Hi, sorry, i gave the wrong URL for the checksum files which should contain sums for .jigdo and .template but do not. A correct URL would be e.g. https://cdimage.debian.org/debian-cd/current/amd64/jigdo-bd/SHA512SUMS (Classical copy+paste error. Of course https://cdimage.debian.org/debian-cd/current/amd64/iso-dvd/ has no .jigdo files and thus needs no checksum entries.) Have a nice day :) Thomas
