Packages for the release of KDE SC 4.9.2 are available for Kubuntu 12.04.1 LTS releases. You can get them from the Kubuntu Backports PPA. They are also in our 12.10 development release.
The Kubuntu community is proud to announce the release of 12.10, the Quantal Quetzal. This is the first release to burst free from the limits of CD sizes giving us some more space for goodies on the image.
It also does away with the alternate installer images, adding advanced partitioning options to the desktop image.
