kde, dependecia e apt-get

Ola!

Fui colocar o kde no ubuntu para rodar alguns programas dele, mas como fui dar apt-get eu interrompi logo no comeco com ctrl+c, depois quando fui fazer de novo ele não consegue montar e baixar as dependencias dando deu a seguinte msg:

ps. Ja tentei o apt-get build-dep kde baixou algumas bibliotecas e nada.
Ja tentei autoclean, check, clean e nada =(

No google achei muita gente perguntando, mas nenhuma resposta que funcione...

root@mceubuntu:/etc/apt# apt-get install kde

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:
