There is an update of Enlightenment 0.21.1 ready in Sparky repository now.

Make upgrade as usually:
sudo apt-get update
sudo apt-get dist-upgrade

If you would like to make fresh installations, run:
sudo apt-get update
sudo apt-get install enlightenment

The present version of Enlightenment still uses EFL 1.17.x.
Just released EFL 1.18 Alpha provides elementary, emotion_generic_players and evas_generic_loaders merged into the EFL package, so they will be removed from Sparky repos when stable EFL 1.18 will be ready.
