I think it was clear, I wrote pre kde4
It's still not clear. Looking at your previous posts it actually looks as if you tried to dist-upgrade a
KDE3 system after activating the
kde4 section in the repo. That would be a very bad idea so you probably didn't. Most likely you installed
task-kde4 in between.
But if so, you didn't tell us. In fact, you haven't told us very much at all. And nobody can try to diagnose your problem unless you tell us
everything that you've done.
(And, looking at the error message in your first post:
kdelibs is in the
kde section while
kdelibs4 is in the
kde4 section. The other dependency errors are more complicated.)
