Не могу ничего установить из-за "printer-driver- ... unmet dependencies"

Я пытаюсь установить GNU screen:

sudo apt-get install screen

Я получаю следующее:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 printer-driver-gutenprint : Depends: cups (>= 1.3.0)
 printer-driver-splix : Depends: cups (>= 1.5.0-3~)
E: Unmet dependencies. [u]Try 'apt-get -f install' with no packages[/u] (or specify a solution).

Далее я выполняю:

sudo apt-get -f install

dpkg: error processing package fontconfig (--configure):

E: Sub-process /usr/bin/dpkg returned an error code (1)

И я не могу установить обновления из Update manager - он выбрасывает предупреждения о " пакеты драйверов принтера имеют ошибки"

Как это исправить?
