Packages for the first release candidate of the KDE Software Compilation 4.4 are available.
Users of the Lucid development release are advised not to upgrade yet, as the packages are only half-built due to a breakage of the underlying graphics stack. The Ubuntu Xorg team is working fervently to resolve the issue as soon as possible.
Users of our stable 9.10 release can install it from the Kubuntu Beta PPA.
For both Lucid and Karmic, virtuoso packages are available. Install both the virtuoso-server and virtuoso-driver packages to enable Nepomuk support.
