Wooo! E17 now have a repo for Ubuntu Jaunty. For some reason, neither the Easy_17 script worked for me, neither did the OzOs repo.
But this, this worked first time!
Go to System –> Software Sources and add the following repo under the Third Party Software tab.
deb http://packages.enlightenment.org/ubuntu jaunty main extras
Now click this clink and download the key :
Open up terminal where ever you downloaded the key and the key :
sudo apt-key add repo.key
Follow up with a :
sudo apt-get update
sudo apt-get install e17
And you away!
