I'm trying to install kdenlive on Ubuntu 9.10. When I do, I get the following error:

Could not mark all packages for installation or upgrade:

From which repository do you try to install?
It looks like you are trying to install kdenlive from sunab2 which is built against KDE 4.4. But you use KDE 4.3.
Take a look at this page:
