«Вы держали сломанный пакет» При попытке установить R

Я знаю, что этот вопрос уже задавался, но все опубликованные ответы не помогли решить мою проблему. Я попробовал следующую команду в Ubuntu 14.04:

sudo apt-get install r-base-core

и получаю:

The following packages have unmet dependencies:
 r-base-core : Depends: libtiff4 but it is not installable
               Recommends: r-recommended but it is not going to be installed
               Recommends: r-base-dev but it is not going to be installed
               Recommends: r-doc-html but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

Я также попробовал это с aptitude:

The following packages have unmet dependencies:
 r-base-core : Depends: libtiff4 which is a virtual package.
The following actions will resolve these dependencies:

I тогда выполнял apt-get upgrade, update и другие материалы, описанные в этого урока . Вот результат команды cat /etc/apt/sources.list:
