HowTo install KDE 3 into Intrepid

Thanks (again) to Madscientist159 the "official" and compatible KDE3 repository is online and ready.
Here the steps to install KDE3 into Intrepid.

(A) If you never installed KDE3 into Intrepid

Open your apt sources.list

Code:

sudo kate /etc/apt/sources.list

And add the following lines at the end of the file:

Code:

#KDE3 Intrepid PPA
deb http://ppa.launchpad.net/kb9vqf/ubuntu intrepid main
deb-src http://ppa.launchpad.net/kb9vqf/ubuntu intrepid main

Save and exit the file. Then do:

Code:

sudo apt-get update
sudo apt-get install kubuntu-desktop-kde3

You'll get a bunch of packages to install, choose y (there is not verification on PPA repositories). When the installation finish, reboot your machine, at the kdm logon choose KDE3 as session.
Done!

(B) If you had installed KDE3 previously following the guide below, do this
Copy your configs:

Code:

sudo cp -R ~/.kde ~/.kde3

Reboot your machine and login into Gnome
Open your apt sources.list

Code:

sudo gedit /etc/apt/sources.list

Remove (if exists) these lines:

and add these lines at the end of the file:

Code:

#KDE3 Intrepid PPA
deb http://ppa.launchpad.net/kb9vqf/ubuntu intrepid main
deb-src http://ppa.launchpad.net/kb9vqf/ubuntu intrepid main

Save and exit the file. Then do:

Code:

sudo apt-get update
sudo apt-get remove kdelibs4c2a gdebi gdebi-core kdebase-data
sudo apt-get install kubuntu-desktop-kde3

You'll get a bunch of packages to remove/install, choose y (there is not verification on PPA repositories). When the installation finish, reboot your machine, at the kdm logon choose KDE3 as session.
Done!
