I want Ubuntu to look like Fedora 15. I have no problem installing and running gnome-shell in Ubuntu 11.10. But its using a different theme than Fedora. Fedora is using the Adwaita theme. I downloaded some Adwaita themes from gnome-look.org and changed them in gmone-tweak-tool but they look a little different. Where can I download the official Adwaita theme? Is there any packages that supply that theme. I think its the default theme in Gnome 3.
