I have installed knoppix yesterday (runs now just fine ).
I started to play around with it (especially with apt-get), and found, that updating KDE isn't all that simple.
After trashing my system with "apt-get dist-upgrade" and playing around by installing and removing of testing and unstable packages for a few more hours I reinstalled it today completelly.

Ok, now I want to install kdict (on my new, cleanly reinstalled knoppix 3.2), and therefore run:
--------------------------------------------------------------------------------
root@terminus:/home/knoppix# apt-get -s install kdict
Reading Package Lists... Done
Building Dependency Tree... Done
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.

Since you only requested a single operation it is extremely likely that
the package is simply not installable and a bug report against
that package should be filed.
The following information may help to resolve the situation:

Sorry, but the following packages have unmet dependencies:
kdict: Depends: kdelibs3 (>= 4:2.2.2-1) but it is not going to be installed
E: Sorry, broken packages
----------------------------------------------------------------------------------------------

the uncommented lines of my sources.list:

# Stable
deb http://ftp2.de.debian.org/pub/debian stable main contrib non-free
deb http://ftp2.de.debian.org/pub/debian-non-US stable/non-US main contrib non-free
# Testing
deb http://ftp2.de.debian.org/pub/debian testing main contrib non-free
deb http://ftp2.de.debian.org/pub/debian-non-US testing/non-US main contrib non-free
# Unstable
deb http://ftp2.de.debian.org/debian unstable main contrib non-free
deb http://ftp2.de.debian.org/debian-non-US unstable/non-US main contrib non-free
------------------------------------------------------------------------------------------------------

apt.conf is unchanged, which means my default release is testing
and yes, I did run apt-get update beforehand.

I tried to install noatun as well, and got the same unmet dependency.

Can anybody help?
