How do I determine where sources mirrors are to use.
I have debian stable but want to update only kde to testing no other packages.
So I have located http://packages.debian.org/testing/kde/
but how do I find the repositories to add to my sources list.
I found this article on qt-kde experimental http://qt-kde.debian.net/
It advises to use apt-spy. But the line it uses to determine the repositories I don't understand how I can utilise it.
# apt-spy -m mirrors.txt -d experimental-snapshots \
-f dists/experimental-snapshots/Release -o /etc/apt/sources.list.d/qt-kde.list
Is this the best way? Is there another way to easily determine and setup sources for debian repositories?
