Debian Upgrade - Plesk Update Fehlermeldung

[catwiesel]

Hallo,

jetzt habe ich gerade ein erfolgreiches Update von Debian Lenny auf Debian Squeeze durchgeführt. Lief ohne Fehler durch.
Plesk lief danach auch noch. Dann halt mal ins Plesk Update reingeschaut, und es waren Updates dar, bezüglich Debian 6.
Ok, lief durch, der ganze Schamott wurde installiert.
Dann nochmals auf das Update gegangen, dann hat er festgestellt, das noch ein Update für Postfix da ist (different Mailserver Postfix). Angeklickt und dann folgender Log-Eintrag:

Error: Sie besitzen die neueste Produktversion und aller ausgewählten Komponenten sind bereits installiert. Installation wird nicht fortgesetzt.

Irgendwie ja teilweise klar, wenn auch nicht ganz logisch. Aber was hat das denn mit dem Postfix Update zu tun?
Jedenfalls wird das Update nicht installiert....

Ah ja, System:
Ein Debian 5 upgegraded auf Debian 6
Plesk 10.2.0
