KDE SC 4.10 has been released today with many improvements and additions, including a new QML-based screen locker, additional KWin effects and scripts thanks to GHNS (Get Hot New Stuff) integration, a new print manager, a new Air theme and wallpaper and many improvements to Kate, Dolphin, Konsole, Okular, Gwenview, Kontact, re-written typing tutor and more.

As usual, the Kubuntu team has been super fast and the latest KDE SC 4.10 is available for Kubuntu 12.10 or 12.04 users in the Kubuntu Backports PPA, so here's how to upgrade.

How to upgrade to KDE 4.10 in Kubuntu 12.04 or 12.10

Before adding the PPA, please note that according to the PPA description, the packages in the Kubuntu Backports PPA might not be tested enough yet, so you may encounter bugs!

The Kubuntu backports PPA provides the latest KDE SC 4.10 for (K)Ubuntu 12.10 and 12.04 (I've only tested it in Kubuntu 12.10). To add the PPA use the following commands:

sudo add-apt-repository ppa:kubuntu-ppa/backports sudo apt-get update

Then, open the Update Manager, make SURE all the packages are selected and install all the available updates. Alternatively, you can also upgrade using the following command (I've stopped using it in posts because on systems with broken packages it can remove packages that's not supposed to):

sudo apt-get dist-upgrade

If you're not using KDE - e.g. if you're using Unity or GNOME Shell, you can install KDE SC 4.10 (firstly, make sure you've added the PPA using the commands above) using the following command:

sudo apt-get install kubuntu-desktop





After all the packages have been successfully installed, it's probably a good idea to restart the system.



If the Plasma theme has some visual glitches when opening the menu, see the When running this command, you'll get a full list of packages that are going to be installed and it would be a good idea to save the list somehwere in case you want to remove KDE, because simply removing the "kubuntu-desktop" package won't be enough. Later on if you want to remove KDE, simply run "sudo apt-get remove PACKAGES", where "PACKAGES" is the list of packages that were installed by the "sudo apt-get install kubuntu-desktop" command.After all the packages have been successfully installed, it's probably a good idea to restart the system.when opening the menu, see the comments below.
