Therefore, i am providing a local KDE repositories synced with Eric's repository in UKDW Repository server (connected to Indonesian IIX networks). It will contain Eric's KDE repository starting from 4.4.4 onward. I hope it can help people having problem to download KDE SC and try it on their computers.
You can also use rsync to get the repository using this command:
rsync -vaz --delete rsync://repo.ukdw.ac.id/alien-kde
Remember, you will need Slackware 13.1 and newer to use KDE SC 4.4.4 and future release.
Enjoy KDE 4.4.4
