Missing file? (resend)

[Klaus Klein <k.klein@gmx.de>]

Hi folks,

 I just tried to update my mirror when I got the following error message:

[100%] Getting: dists/experimental/non-free/binary-i386/Packages.diff/2006-12-04-2017.23.gz      # failed:Failed to open file.
dists/experimental/non-free/binary-i386/Packages.diff/2006-12-04-2017.23.gz failed md5sum check, removing

dists/experimental/non-free/binary-i386/Packages.diff/2006-12-04-2017.23.gz failed sha1sum check, removing

and

Errors:
 Download of dists/experimental/non-free/binary-i386/Packages.diff/2006-12-04-2017.23.gz failed: Failed to open file.
 dists/experimental/non-free/binary-i386/Packages.diff/2006-12-04-2017.23.gz failed sha1sum check, removing
Failed to download some Package, Sources or Release files!

Therefore I checked on a few mirrors (ftp.us.debian.org, ftp.de.debian.org, ftp2.de.debian.org, debian.swordcoast.net) and the file is actually 
not in the refered directory.

Nevertheless the 'Index' file in the directory is listing the file:

 7c84589ff641c61f86a020e071923a86d9b5ff9a   12263 2006-12-04-2017.23

Anything I'm doing wrong?
Am I the only one with that problem?

Rgds,
Klaus
