kde install

[Norman Cohen <norman@harman.u-net.com>]

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  resumed 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
