Kindhearted Linux Debian users, please help to debug and fix this issue !

I use Debian with KDE and while trying to install almost any package, I get the following error.


root#apt-get install sudo
Reading Package Lists... Done
Building Dependency Tree... Done
sudo is already the newest version.
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
kubuntu-default-settings: Depends: kde-style-lipstik but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

are you running Kubuntu or Debian?

a lot of times the packages dont mix well, can you post your /etc/apt/sources.list ?

This happens from time to time, most often if you're running the unstable distribution or are mixing packages from different sources.
The brute-force method are to run:
If it's a package that you don't really need you could also try 'apt-get remove kde-style-lipstik' which might work.
