Problems with Java PPA.

[Crabaroni]

In synaptic it says the sun-java6-jre package is broken. I re-downloaded the repository but that doesn't help. I can't install anything. When I try it gets to 99% and cannot get the "headers". This is what happens when I sudo apt-get update.

It seems you have more than one "package manager" running.
Make sure you dont have synaptic package manager, or software center open when doing this in the terminal.
If you do, you will get the
E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?message.

Also,
You might want to look into ubuntu restricted extras.
