HowTo Install KDE 3 into Kubuntu Intrepid

[dentaku65]

Prologue
I switched to Kubuntu Intrepid from Hardy and I kept KDE 3 because, in my opinion, KDE 4 is not ready to day-by-day pc operations.

This is not a post against KDE 4, so please do not start flame war about KDE.

I understand at large the reasons why Kubuntu team make the decision to switch the WM into KDE 4 and to do not include KDE 3 anymore; in my view this is a simply wrong decision, but it's ok.
Anyway, because I like very much *ubuntu philosophy and KDE, I found a way to continue to use my distribution at the ultimate release (Intrepid) with my favorite (at the moment) WM, KDE 3.

First of all I must say a big thanks to Madscientist159 that, without his precious works, the solution to use KDE 3 into Intrepid was not possible. Again, Madscientis159, in the full sense of *ubuntu community, invest his time and knowledge into this possibility.

I did the following steps personally, but I do not guarantee that this will work for you, but if I can I'll try to help you.
Please follow the steps indicated if you are a quite experienced user of the system.

The upgrade from Hardy to Intrepid
When you are still in Hardy install Gnome environment

sudo aptitude install ubuntu-desktop

Reboot your machine and log into Gnome
Open a terminal window and do:

sudo apt-get update
sudo apt-get dist upgrade

Accept the updates if any.
Download on your desktop my source list file sources.txt (available at the end of the post); the repositories in the sources.txt are the official one from Ubuntu; then do:

sudo cp ~/Desktop/sources.txt /etc/apt/sources.list

Then upgrade the system from Hardy to Intrepid: To upgrade from Ubuntu 8.04, press Alt+F2 and type in "update-manager -d" (without the quotes) into the command box. Update Manager should open up and tell you: New distribution release '8.10' is available. Click Upgrade and follow the on-screen instructions.

(I did not make the command above to upgrade, but I used apt-get, the comand above is the official one anyway)

At the end of installation reboot your machine and log into Gnome. Now you are in Intrepid

Install KDE 3 into Intrepid
Attention! Install KDE 3 will REMOVE KDE 4
Open the sources.list file

sudo gedit /etc/apt/sources.list

And add the following lines (the Madscientist159 repository) at the end and save/close the file:

###KDE3 on Intrepid
deb http://apt.pearsoncomputing.net/ intrepid main
deb-src http://apt.pearsoncomputing.net/ intrepid main

Add GPG to the repository:

wget http://apt.pearsoncomputing.net/public.gpg
sudo apt-key add public.gpg

Then do:

sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get install kde3 jockey-kde

Reboot your machine and log into KDE; now you are in KDE 3 in Intrepid

Annoyances
Fix KDM login window

sudo ln -s /usr/share/apps/kdm/themes/Krystal/ /usr/share/apps/kdm/themes/kubuntu

Remove kde applet for network-manager (is not working)

sudo apt-get remove knetworkmanager network-manager-kde

Add nm-applet of Gnome into KDE

sudo ln -s /usr/bin/nm-applet ~/.kde/Autostart/nm-applet

Probably you must reconfigure kicker (KDE app bar and some stuff in kcontrol like fonts and style), if you had previously (in Hardy) installed compiz+emerald the configuration will be kept intact.

Reboot to get your networking works under KDE
Basically now you have finished, just add Medibutu repositories

sudo wget http://www.medibuntu.org/sources.list.d/intrepid.list -O /etc/apt/sources.list.d/medibuntu.list
sudo apt-get update && sudo apt-get install medibuntu-keyring && sudo apt-get update
sudo apt-get dist-upgrade

Accept the updates if any.

Do you still want KDE 4?
You can use the Nightly Neon ppa repositories (no GPG for authenticated packages)
Open sources.list

sudo kate /etc/apt/sources.list

And add the following lines at the end of the file, then save/close the file:

###Amarok2 & KDE4 Nightly Neon!!
deb http://ppa.launchpad.net/project-neon/ubuntu intrepid main

Then do:

sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get install kde-nightly

Reboot the machine. Now you can choose 3 WM at the login window:

• KDE 3
• KDE 4 (Nightly)
• Gnome

That's it.
