problems with apt-get

["Sockmonkey" <rrabien@telus.net>]

So I do:

[rabbit]root%apt-get install kde
Reading Package Lists... Done
Building Dependency Tree... Done
kde is already the newest version.
You might want to run `apt-get -f install' to correct these:
The following packages have unmet dependencies:
  kdeaddons: Depends: kontact-plugins (>= 4:3.2.3-2) but it is not going to
be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify
a solution).

So then I do:

[rabbit]root%apt-get -f install
Reading Package Lists... Done
Building Dependency Tree... Done
Correcting dependencies... Done
The following extra packages will be installed:
  kontact-plugins
Suggested packages:
  kdeaddons-doc-html
The following NEW packages will be installed:
  kontact-plugins

And now I am stuck in a state where I can't install any packages. Any ideas
how to continue from here?
Thanks
