Packages for the release of the KDE Software Compilation 4.7.1 are available for Kubuntu 11.04. Packages for oneiric have been available for a while, but the backports for 11.04 took longer than expected, we apologise for the delay.
Bugs in packaging should be reported to kubuntu-ppa on Launchpad. Bugs in the software to KDE.
Users of 11.04 can install it from the Kubuntu Backports PPA.
