Потерянные настройки меню и единство линз после удаления Gnome 3

Я установил gnome 3 в Ubuntu 13.10 - позже решил удалить его. Теперь все прошло. Когда я щелкаю правой кнопкой мыши по рабочему столу, я не могу получить доступ к настройкам, и все линзы единства отсутствуют, кроме сообщений в социальных сетях и сетях. Поэтому я не могу получить доступ ни к каким программам из единой панели запуска, а только к тому, что я прикрепил к боковой панели.

В терминале я пробовал

apt-get install gnome-control-center

, но я получаю следующее сообщение

The following packages have unmet dependencies.
 gnome-control-center : Depends: gnome-control-center-data (< 1:3.7) but 1:3.8.3-0ubuntu1~raring2 is to be installed
E: Unable to correct problems, you have held broken packages.

Я думаю, когда я удалил Gnome 3, он сломал некоторые пакеты, и я не уверен, как их вернуть.

Я установил гном 3 из PPA

sudo apt-get install ubuntu-desktop на выходах
