Install updated packages in Ubuntu 11.10 via GNOME 3 PPA
Ubuntu 11.10 was launched with GNOME 3.2, but, due to their late arrival, some newer GNOME packages didn't land in Oneiric.
As for Oneiric Ocelot, for these new packages a PPA has been created that offers mainly GNOME 3.2 packages, like Epiphany Web Browser 3.2.1, Totem Movie Player 3.2.1, GNOME Documents 0.2, Tracker 0.12 (app useful for indexing files), Xchat GNOME, as well as various updated libraries.
As for Ubuntu 12.04, the same PPA will deliver GNOME 3.3/3.4 packages that will not land in the default install due to Precise's LTS nature (focusing mainly on stability, the default packages are carefully chosen).
How do we install the new packages?
Add the following official PPA (Oneiric)
sudo add-apt-repository ppa:gnome3-team/gnome3
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install epiphany-browser
sudo apt-get install totem
sudo apt-get install gnome-documents
sudo apt-get install xchat-gnome
