also when booting the system complaines:
"Check your locale settings: ... default locale not valid".

especially doing 'apt-get -f install' leads to the same result.

any sugestions?

PS: Antworten in deutsch sind ok.
Use dpkg -i --force-overwrite /var/cache/apt/archives/kdebase-data....deb to force the overwrite of the kde package then dpkg --configure -a to configure the packages left unconfigured when the error happened. BTW it is better to see the output of the error rather than you paraphrasing it so if you can post the output of errors when they happen.
