Ubuntu – Gnome Shell Extension Empty

Here is the situation. Changed unity shell to gnome shell. Installed the gnome tweak tool, installed the shell extension, themes, etc…everything i normally need to do that is installed

When i go to gnome tweak tool, and click on shell extension, the right list is empty

I've surfed the web and questions for answer. Yes, i did restart my pc after installing everything, even restarted a couple of time.

Yes, i clicked the cog and chose GNOME instead of Ubuntu.

To no avail, i can't seem to see what is supposed to be on that right menu. I saw some screenshot, and i know it is supposed to be filled with radio buttons and such

I've tried the suggested answer here – Gnome Tweak Tool does not show extensions but this is the result:

   cd ~/.local/share/gnome-shell/extensions/
   cd ~/.local/share/gnome-shell/extensions/: No such file or directory 

I installed the following gnome-shell extensions which are not appearing in gnome-tweak-tool:

gnome-shell-extensions-alternative-status-menu
gnome-shell-extensions-common
gnome-shell-extensions-user-theme

All of that info gotten from Synaptic, which i also installed!
All package were installed in root mode, updates and upgrades done

Also, the terminal just popped an error as i tryied to get into the tweak tool, first time it pop me the error:

I also tryied "sudo apt-get remove gnome-tweak-tool" and "sudo apt-get install gnome-tweak-tool" to no avail. Still the same long error message

Help?

EDIT:
I have scrapped the whole virtual machine, and reinstalled it.

30 GB of hard drive

Ubuntu 11.10

728 MB of video memory

Home folder not encrypted

Here is what i have done:

sudo apt-get install gnome-shell

Reboot

Boot into GNOME

sudo add-apt-repository ppa:webupd8team/gnome3

sudo apt-get update

sudo apt-get install gnome-tweak-tool

And still the same!
