Here’s how to install the newly-release KDE 4.3 in Ubuntu Jaunty.Open up your sources.list file: sudo nano /etc/apt/sources.list add the following line at the bottom of the file: deb http://ppa.launchpad.net/kubuntu-ppa/backports/ubuntu jaunty main Save the file and do a sudo apt-get update && sudo apt-get dist-upgrade
The Update manager in Jaunty tends to show up unexpectedly now and then. You close the window by reflex. But what if you didn’t have to cloes it anymore? Disable the application’s pop-up window by launching gconf-editor then go to apps > update-notifier and uncheck the auto_launch value.
