I am trying to install ANewStart GNOME shell themes on Ubuntu 11.10.

I have installed gnome shell extension for themes:

sudo add-apt-repository ppa:webupd8team/gnome3 sudo apt-get update
sudo apt-get install gnome-shell-extensions-user-theme

I got the instructions from here ANewStart GNOME Shell Theme + AwOken Icons Theme = Pure Art.

But when I go to "Advanced Settings -> Shell Extensions" its empty... There is nothing.

Also there is a orange triangle sign next to Shell Theme drop down in Advanced Settings -> Theme.

When I try to run the gnome-tweak-tool from terminal I get following error:

imresh@imresh-laptop:~$ gnome-tweak-tool

CRITICAL: Error parsing schema org.gnome.shell

Please help me in fixing this. I have also restarted the computer many times it does not make a difference.
