Hi,it seems that dpkg got stocked somewhere with a package ,when i try to do apt-get upgrade ,to general upgrade some package i have installed on Debian Squeeze ,i got this ugly error

ost installation script return an error code (1),and doesn't let me to do some install ,it seems that lsh server can't start ,this is the error sorry is not in english but you'll figure out :
Code:

I try to do apt-get -f install lsh-server but the error return again:
I read on web a Debian site (i don't remember) i got it when sysv-rc configure to migrate to dependency based boot system:I had do it first "apt-get upgrade"
and that's why sysv-rc configure:
Code:
Unable to migrate to dependency based boot system
Tests have determined that problems in the boot system exist which prevent migration to dependency based boot sequencing. It is recommended to migrate for the following reasons:
* the order of boot and shutdown is calculated dynamically, using dependency information declared within each init.d script, which ensures optimum and correct boot sequence for the set of installed packages , * protection against problems introduced by new or upgraded packages by preserving the boot sequence when problems are detected; the boot sequence is only modified if it is safe to do so
If the reported problem is a local modification it needs to be fixed manually. If it's a bug in the package it should be reported to the BTS and fixed in the package. See http://wiki.debian.org/LSBInitScripts/DependencyBasedBoot for more information about how to fix the problems preventing migration. To reattempt the migration process after the problems have been fixed, run 'dpkg-reconfigure sysv-rc'.
The following problems were detected: package jackd left obsolete init.d script behind, package aumix-common removed by not purged, package dhcdbd removed by not purged, package fam removed by not purged, package lisa removed by not purged, package nvidia-glx removed by not purged, package postgresql-8.3 removed by not purged, package samba removed by not purged, package wdm removed by not purged, package winbind removed by not purged, insserv: script xfstt service xfs already provided!, insserv: script xfstt: service xfstt already provided!, insserv: script postgresql-8.4: service postgresql already provided!, insserv: script postgresql-8.4: service postgresql-8.4 already provided!,
.
So now i'm lost, i had follow the website provided in this log
http://wiki.debian.org/LSBInitScript...dencyBasedBoot but the error i'm talking it didn't disappear .
Thank you and sorry for the big log.
