Dear Tom,

Indeed I am always a bit nervous when I have to use CLI instead of GUI as I am 
not that geek experienced...

However, in while comparing the sources listed in the Kpackage and in the 
source.list file, I found a lot of differences.  In the GUI one I have just few 
of the sources listed, compared with what I can read in the source.list file...
