SOLVED BY MYSELF I give the explanations to the other beginners : I typed the following lines while I was connected to the web
""If you have a program that does not work, then type first like this :
1. sudo apt-get remove [program_that_does_not_work]
""and type lines 2 to 5 (look under) to clean your system
**else begin directly at line 2 till 5
2. sudo apt-get clean 3. sudo apt-get update 4. sudo dpkg --configure -a 5 sudo apt-get upgrade
Nice ! NB : Caution : "gnome" programs do not work under KDE. Then avoid to download them. else the OS becomes unstable.
