I've tried everything but it wont install.
Tried to put:
deb http:||download.kde.org/stable/3.1.3/Debian stable main
in sources.list and the apt-get update

(returns)
debian:/etc/apt# apt-get update
Hit http:||security.debian.org stable/updates/main Packages

Then tried apt-get install kde gives me that I already have the lates KDE.
Well ok. Somebody told me that there isn't meta-package for KDE,
and he also told that he used:
apt-get install arts kdelibs kdebase kdegraphics kdeadmin
well. I tried this and ehat I got:

debian:/etc/apt# apt-get install arts kdelibs kdebase kdegraphics kdeadmin

Sorry, kdebase is already the newest version.
