Re: What mirror to use with archived jigdo DVD images ?

I had a similar suspicion but failed yet to write a reverse function to
decode the MD5s in the .jigdo file. It's a 6-bit format but not base64.
An encoder is in libjte/jte.c as base64_dump(). A decoder should be in
jigdo-file, but i cannot find it.

Yep. The next jigdo-lite run yields:
Found 2 of the 2 files required by the template
Successfully created `debian-6.0.7-amd64-DVD-1.iso'
The fact that you got this far is a strong indication that `debian-6.0.7-amd64-DVD-1.iso'
was generated correctly. I will perform an additional, final check,
which you can interrupt safely with Ctrl-C if you do not want to wait.
OK: Checksums match, image is good!
sha256sum too yields the correct checksum from the .jigdo download site.
To understand what was going on: Is this theory correct ?
- Regardless which mirror URL i told jigdo-lite, it tried to fetch the
problematic packages from your server.
- jigdo-lite (or rather its backend jigdo-file) did not tell that the
MD5 of the downloaded packages are wrong.
But why did my first attempt yesterday yield 7 missing files, when i used
Debian mirror http://ftp.de.debian.org/debian/ ?
Another glitch somewhere else ?
That mirror has not many of the desired files, but i can see in the log
that missing files get later found on us.cdimage.debian.org/cdimage/snapshot.
The next try with mirror archive.debian.org/debian/ fetched from there
The two offending files yielded 404 and were then fetched from
In the log i see that ialready the first try got all 7 files from
us.cdimage.debian.org but somehow did not graft them into the ISO.

Whatever, i will now ask Nicholas Geovanis on debian-user to try again.
Have a nice day :)
