galaxium

I tried to install galaxium by adding this two line to ((/etc/apt/sources.list)):

deb http://ppa.launchpad.net/galaxium/ubuntu jaunty main
deb-src http://ppa.launchpad.net/galaxium/ubuntu jaunty main

And after typing:

sudo apt-get update
sudo apt-get install galaxium

the set up didn't start and the output was

Reading package lists... Done
Building dependency tree
Reading state information... Done
Package galaxium is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package galaxium has no installation candidate

How can I install galaxium on my Ubuntu 9.04
