dist-upgrade problem with conflicting packages coreutils and shellutils

[Gerhard Gaussling <ggrubbish@web.de>]

Hi all,

I got a wired problem upgrading woody to sarge. I'm not able to 
upgrade shellutils.

I had setup preferences and sources list for pinning with unstable. 
This might be the reason of my problem.
Now I got only testing and stable/upgrade (security) in my sources 
list and I moved preferences to preferences.old.

Nevertheless I got these results:

  debian:/home/gerhard# apt-cache policy coreutils
coreutils:
  Installed: 4.5.1-2
  Candidate: 4.5.1-2
  Version Table:

What can I do now to progress with dist-upgrade.
dselect also runs into a loop with this problem.

Any advice is apreciate.
Thanks in advance
