Sure, but all the URLs listed in the log are working, so it seem
strange that one of them give 404.

It is bogus, as all the URLs in the log are working when I test them
manually, and it is close to impossible to figure out what URL was
failing.

Yes.  Only found the two mentioned in the patch, and neither seem to
use a non-existing URL. :/

I disagree.  The error in question is almost useless.  There is no way
to see which URL was missing, and the message show up in the wrong
location in the log.  A useful error message would make it possible to
figure out what is wrong.  This one do not. :(

If the error message continue to come from d-i, we need to filter it
out in debian-edu, but I thought it best to try to get rid of it
first.

Happy hacking,
