I am trying to install two software:

1. Marble - a software for studying maps and globe and


2. KPatience - a card game.

Both seem to start the installation nicely but as the download progresses suddenly it stops asking me to check my Internet connection, which is fine. Both these software are part of some KDE package as I understood from their description.

I don't know much about that and I am a new user to Linux. Someone please help me with this problem. I am using Ubuntu 12.04
