Cannot edit sources.list for KDE4 install

[Northsider]

I cannot edit my sources.list file when I am following the instructions to install KDE4. I get a permission error, which I do not know how to change.

Any ideas?

You didn't specify, and I don't assume, so, did you edit the file as root (required)? The easiest way is to open a console and type:

kdesu kate /etc/sources.list

As the first user (installed the system) you are. But, then again, your working with KDE4 which still isn't even a Beta yet. :P
