On www.debian-desktop.org a new version of KDE 4 is available as backport for Debian/GNU stable.
This time a lot of changes have been made:
- Package Version will allow upgrade to squeeze or sid (Packages are tagged with ~mea)
- All required packages have been recreated. You will need one line in your sources.list only
KDE 4.2.4 is running fine on my workstation for quite some time.
The update from the debian-desktop.org Version 4.2.3 to Version 4.2.4 requires manual interaction due to some files which have been moved to another package.
even though that I am co-working with the Debian pkg-qt-kde team does not mean that these are official packages!
The repository is and will always be unofficial.
Have fun with KDE 4.2.4
