window manager won't install

[MMe]

Kubuntu didn't install comlpletely, I upgrated from 13.10 to 14.04 but when I open a browser, I can't switch to fullscreen and I have no window manager to close the application.
When I try to install a Window manager in synaptic it says that I have broken packages but I cannot restore them.
Maybe it'll be resolved when I get more updates, I wait for a week, and if it is not resolved I do a clean install.

you do have an unofficial libwayland-egl1-mesa installed which was blocking the upgrade of kde-window-manager, so to fullfill the other requirements the upgrader decided to remove kde-window-manager as there was no way to upgrade it. to resolve this situation you'll have to downgrade libwayland-egl1-mesa. if you need help with that please ask on a forum or on IRC.
