Thank you for your update. Please note that 'apt-get upgrade' will not install *NEW* packages or remove currently-installed ones. You should either run 'apt-get dist-upgrade' for full update, or 'synaptic' -- and be EXTREMELY careful on what will get done: on an Ubuntu version in development, you can get a new package that will force the removal of not-yet-updated packages... I do it, but I am extremely careful on what gets selected to be done.

Using 'update-manager' is usually much safer.
