apt-get Problem

[Gerhard Engler <gerhard.engler.debian@gmx.de>]

Hallo Mailingliste,

ich habe auf meinem Rechner Debian testing installiert. Leider läßt sich 
das Programm apt-listchanges nicht installieren.

Nach einem apt-get -f install apt-listchanges python-apt 
libapt-inst-libc6.3-5-1.0 libapt-pkg-libc6.3-5-3.3

erhalte ich immer die Fehlermeldung:

Reading Package Lists...
Building Dependency Tree...
Note, selecting apt-utils instead of libapt-inst-libc6.3-5-1.0
Sorry, apt-utils is already the newest version.
Note, selecting apt instead of libapt-pkg-libc6.3-5-3.3
Sorry, apt is already the newest version.
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

Sorry, but the following packages have unmet dependencies:
  python-apt: Depends: libapt-inst-libc6.3-5-1.0
              Depends: libapt-pkg-libc6.3-5-3.3

Wie löse ich das Problem?

Vielen Dank!


Gerhard
