Почему я не могу установить проприетарные драйверы?

Я следую этому руководству по установке Bumblebee на свой Dell n5110, но я получаю эту ошибку, когда я достигаю четвертого шага учебника. Что я делаю неправильно или что еще мне нужно делать?

    The following packages have unmet dependencies:
      bumblebee-nvidia : Depends: nvidia-driver but it is not installable or
                         nvidia-glx but it is not installable or
