I was trying to install kde-full when the libc had some unmet dependencies error. When saying
sudo apt-get install kde-full

the terminal has this in the end

libc6 : Depends: libc-bin (= 2.15-0ubuntu10)   
libc6:i386 : Depends: libc-bin:i386 (= 2.15-0ubuntu10)   
libc6-dev : Depends: libc6 (= 2.15-0ubuntu10.3) but 2.15-0ubuntu10 is to be installed  
libc6-i386 : Depends: libc6 (= 2.15-0ubuntu10.3) but 2.15-0ubuntu10 is to be installed  

When running sudo apt-get -f install, this shows up at the end

De-configuring libc6:i386 ...

E: Sub-process /usr/bin/dpkg returned an error code (1)  

Any suggestions how to fix this. I don't desire to have kde-full anymore; only that other installations should work. I've done sudo apt-get update several times, so those suggestions can be kept away

UPD : here is output of dpkg configure
