hi people, I can confirm the same thing here in Ubuntu 12.10 with Gnome3.5!! And throguh looking at the Synaptic, I found out that all packages referring to Gnome and Gnome-Shell are already up to version 3.5 except of gnome- tweak-tool.
So I would suggest, that gnome-tweak-tool should be upgraded to version 3.5 because of dependcy-problems. the properties of gnome-tweak-tool say this: needs python2.7 needs python (>=2.7.1-0ubuntu2) needs python (>2.8) needs gsettings-desktop-schemas (>=3.3.2) needs gnome-shell-common (>=3.4) needs python-gi (>=3.2.1) needs gir1.2-gtk-3.0 needs gir1.2-gconf-2.0 Then I checked in my Synaptic and found out, that these package-versions are installed by default: python2.7 (packe-version 2.7.3-0ubuntu5) python2.7.1 no package available python2.8 no package available python3 (package-version 3.2.3-0ubuntu1) gsettings-desktop-schemas (package-version 3.5.2-0ubuntu1) gnome-shell-common (package-version 3.4.1-5ubuntu1) python-gi (package-version 3.3.2-1) gir1.2-gtk-3.0 (package-version 3.5.4-0ubuntu1) gir1.2-gconf-2.0 (package-version 3.2.5-0ubuntu2) This shows up, that there are dependency-problems!! for example at the package gnome-shell-common. This package is still version 3.4 although the other packages of gnome-shell are already version 3.5!! As next, the package python-gi is still version 3.3.2-1, although other packages of GNOME are already version 3.5!! As firther thing, the package gir1.2-gconf-2.0 is still version 3.2.5 and needs to be version 3.5!! So the following packages need to be upgraded: gnome-shell-common gnome-tweak-tool (installed version 3.4 but needs to be version 3.5!!) python 3 (upgrade from version 3.2.3 to version 3.5!!) python-gi (version 3.3.2-1 to version 3.5!!!) gir1.2-gconf-2.0 (version 3.2.5 to version 3.5!!!) Then I found, that no packages for python 2.7.1 and python 2.8 are available. But these are needed as dependency for gnome-tweak-tool as the output states abouve. So this needs to be fixed, that gnome-tweak-tool can come back to live!!!
