I followed the instructions here, however I got 404 not found error checking for updates:
W:Failed to fetch http://ppa.launchpad.net/ubuntugnometeam/gnome3/ubuntu/dists/natty/main/source/Sources 404 Not Found,
W:Failed to fetch http://ppa.launchpad.net/ubuntugnometeam/gnome3/ubuntu/dists/natty/main/binary-i386/Packages 404 Not Found,
E:Some index files failed to download. They have been ignored, or old ones used instead.
Thus I couldn't even start the installation. Anybody know how to perform a full installation?
Now got new error:
W:Failed to fetch http://ppa.launchpad.net/gnome3-team/gnome3/ubuntu/dists/natty/main/i18n/Translation-en Connection failed, E:Some index files failed to download. They have been ignored, or old ones used instead.
And these are all the files in sources.list.d:
