Run the following command:

sudo apt-get -f install

to force the install of the packages that didn't get installed because of the error. Then, run the installation command again.

Then, apt-get -f install back and forth. Most probably you'll get through.

If you are using GNOME 3.6, it's normal if you receive Extension doesn't support shell version because GNOME 3.6 it's too new so the developer will need to rewrite it to make it support with the new version.
