I want to install Trinity (the fork of KDE 3.x) on Ubuntu 12.04. I tried adding the PPA and doing sudo apt-get install kubuntu-default-settings-trinity kubuntu-desktop-trinity, but I got an error:
Reading package lists... Done
Building dependency tree
Reading state information... Done

E: Unable to correct problems, you have held broken packages.
I don't get step 5 back on the PPA's overview page, look for the Signing key heading. You'll see something like:
1024R/72D340A3 (What is this?)
Copy the portion after the slash but not including the help link; e.g. just 72D340A3
Here is the link if you want to help me: https://quickbuild.pearsoncomputing.net/~trinity/+archive/trinity-nightly-builds/
At the moment there is no packages for ubuntu 12.04. The reason you are getting this error is because the packages you are installing don't exist. You can try using the 11.10 instructions for install ubuntu, but it's not guaranteed to work or not cause issues with installing:
http://www.trinitydesktop.org/wiki/bin/view/Documentation/UbuntuBinaryInstallation
There is now a new desktop environment called “Trinity” which is basically the further development of KDE3.
You can install it by following the following instructions.
Add these lines to the end of your sources list, if you are running an older version of ubuntu please see this page before continuing.
Next you want to add the GPG Signing Key.
Next simply make sure you are up-to-date and install Trinity.
Thats it you should now be able to logout, switch sessions and login to KDE3. Enjoy! =)
It doesn't work look the error:
