MD5Sum mismatch

[Gilles <gilles@harfang.homelinux.org>]

Hello.

I've encountered a "mirror" bug, trying to install
the following packages:
 libclass-autouse-perl
 libclass-container-perl
 libparse-recdescent-perl

For example:

# apt-get install libparse-recdescent-perl
Reading Package Lists... Done
Building Dependency Tree... Done
The following NEW packages will be installed:
  libparse-recdescent-perl
0 upgraded, 1 newly installed, 0 to remove and 363 not upgraded.
Need to get 123kB of archives.
After unpacking 483kB of additional disk space will be used.
Get:1 ftp://ftp.belnet.be sarge/main libparse-recdescent-perl 1.94-4 [123kB]
Fetched 123kB in 0s (191kB/s)
Failed to fetch ftp://ftp.belnet.be/debian-amd64/debian/pool/main/libp/libparse-recdescent-perl/libparse-recdescent-perl_1.94-4_all.deb  MD5Sum mismatch
E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?


The maintainer declines responsibility for this kind of problem,
and directed me to this list.

I did what was suggested in an earlier post on a similar subject:

# md5sum libparse-recdescent-perl_1.94-4_all.deb
ab7be2fc61a0e7f8fca232fac1fb8e03  libparse-recdescent-perl_1.94-4_all.deb
dusk:~# apt-cache show libparse-recdescent-perl | grep MD5
MD5sum: 2033ad73707f602e0fdc0d23c3c946b8

So indeed there is a mismatch. 2 mirrors ("ftp.belnet.be" and
"ftp.nl.debian.org") have the problem.
Who is able to fix the situation?

Best regards,
Gilles
