Debian has KDE 4.7.4 in Experimental repositories; install instructions

Not in the Debian-KDE repos that had 4.7.2, but in the official Debian Experimental repositories, KDE 4.7.4 has been released!  You need to be running Debian Sid to take advantage of this and be aware that these packages aren't fully vetted and may break your world.

First make sure that you're running Sid.  Add these three lines (or similar for your local repos) to the file at /etc/apt/sources.list making sure to adjust if you don't want the non-free packages, etc:

## EXPERIMENTAL aptitude -t experimental install digikam

deb http://debian.uchicago.edu/debian/ experimental main contrib non-free 

deb-src http://debian.uchicago.edu/debian/ experimental main contrib non-free 

Run aptitude update to update the catalog, and then we need to update the system and specify that we want the Experimental packages (for system stability reasons):



shell~$ sudo aptitude -t experimental dist-upgrade
