Installing KDE 4.2 on Ubuntu 8.10
The KDE team announced the general availability of KDE 4.2 on Tuesday. The folks at Kubuntu were kind enough to have been hosting apt repositories of the beta releases all along, and they have followed by offering a binary release distribution as well.
To install KDE from the Kubuntu repository
Open sources.list in a text editor:
$ sudo vi /etc/apt/sources.list
Add the following line to sources.list to add the new repository
$ deb http://ppa.launchpad.net/kubuntu-experimental/ubuntu intrepid main
Update the apt repository cache
$ sudo apt-get update
Then it is just a matter of running apt-get to install everything
$ sudo apt-get install kde
I got hung up on the last step, since I didn’t know that simply installing `kde’ would pick up version 4.2 once the new repo had been added to sources.list.
