Failure to upgrade to samba backport

[Nicolas KOWALSKI <niko@petole.demisel.net>]

Hello,

When I try to upgrade my current samba installation to the one
available in backports it fails with some dependencies errors, and I
do not see how to resolve them:


petole:~# apt-get -t lenny-backports install samba

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:

The following packages have unmet dependencies:
  samba: Depends: samba-common (= 2:3.3.4-1~bpo50+1) but  2:3.2.5-4lenny2 is to be installed
         Depends: libgnutls26 (>= 2.5.9-0) but 2.4.2-6+lenny1 is to be  installed
         Depends: libgssapi-krb5-2 (>= 1.6.dfsg.2) but it is not  installable
         Depends: libk5crypto3 (>= 1.6.dfsg.2) but it is not  installable
         Depends: libkrb5-3 (>= 1.7dfsg~alpha1) but it is not  installable
         Depends: libtalloc1 (>= 1.2.1) but 1.2.0~git20080616-1 is to  be installed
E: Broken packages


What can I do to resolve these dependencies errors ?



My /etc/apt/sources.list is:
