I am currently downloading KDE 4.83 from https://launchpad.net/~kubuntu-ppa/+archive/ppa?field.series_filter=precise. In the past updates like this have been in the backports ppa. I was waiting to add the backports ppa since it doesn't have any 12.04 packages yet. Which ppa will contain the KDE updates/upgrades in the future? Thanks, Chuck
