Я не могу установить инструмент тонкой настройки единицы в Ubuntu, даже склонной - получают установку-f

Я пытался установить инструмент тонкой настройки единицы в своей Ubuntu, но это всегда перестало работать. Я искал вокруг Google, и посмотрите все форумы, но никакие работы решения. Я думаю, что Ubuntu становится багги, вот моя терминальная запись:

    mrna@MrNA:~$ sudo apt-get install unity-tweak-tool 
[sudo] password for mrna:

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 gnome-tweak-tool : Depends: gnome-settings-daemon but it is not going to be installed
 unity-tweak-tool : Depends: unity-webapps-common but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
mrna@MrNA:~$ apt-get -f install
E: Could not open lock file /var/lib/dpkg/lock - open (13: Permission denied)
E: Unable to lock the administration directory (/var/lib/dpkg/), are you root?
mrna@MrNA:~$ sudo su
root@MrNA:/home/mrna# apt-get -f install

The following packages were automatically installed and are no longer required:
  hwdata libboost-filesystem1.58.0 libmirclient9 libmircommon5 libmirprotobuf3
  signon-plugin-password
Use 'sudo apt autoremove' to remove them.
The following additional packages will be installed:
  gnome-settings-daemon
The following NEW packages will be installed:
  gnome-settings-daemon
