How to update from Gnome 3.4.1 to 3.6?

I use Ubuntu 12.04 with Gnome 3.4.1.

I've tried to upgrade to Gnome 3.6 to no avail.

I added this to my /etc/apt/sources.list file:

deb http://ppa.launchpad.net/gnome3-team/gnome3/ubuntu precise main

Then I ran

sudo apt-get update 
sudo apt-get upgrade

Then restarted the system.

But when I run:

gnome-shell --version

It continues to print

GNOME Shell 3.4.1

What can I do ?

I need to upgrade to 3.6 in order to be able to use an extension that allows the app switcher to only switch between apps in the current workspace.

First you need to remove the line that you added to the sources.list. PPAs are added differently. From a terminal add the PPA by doing: sudo add-apt-repository ppa:gnome3-team/gnome3 and sudo add-apt-repository ppa:ricotz/testing . Then run sudo apt-get update and sudo apt-get upgrade.

To update to Gnome 3.6, you need to add these two PPAs:

sudo add-apt-repository ppa:ricotz/testing
sudo add-apt-repository ppa:gnome3-team/gnome3

Then run:

sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade

• The dist-upgrade command is needed because packages that aren't installed must be pulled in as dependencies for the upgrade to work. However, this also makes it possible for packages to be removed--which might also be necessary--so it's important to look at what packages, if any, it says will be uninstalled.
