I  try to install KDE  on potato 2.2 r4 by putting the following
in my  sources.list:
deb http://kde.tdyc.com potato main crypto
then wvdial

and then running

#apt-get update
#apt-get install task-kde
however as my modem is slow I have to download a number of times and 
hope the download will  be OK! I notice that /var/cache/apt/archives 
shows a number of downloads. How do I proceed? I am a complete newbie 
and would really appreciate help. Thanks Norman Cohen
