Не могу установить Cuda в Ubuntu 14.04 из-за конфликтов пакетов

Я считаю, что у меня та же проблема, что и в этой ветке, но я пробовал перечисленные шаги, и я не могу решить эту проблему.

Я использую Ubuntu 14.04 64bit на собственном рабочем столе с 4 Гб оперативной памяти DDR3, процессором Intel i3 с тактовой частотой 3,3 ГГц и GeForce GTX 950 с драйвером nvidia 352.63 на вкладке дополнительных драйверов в разделе «Программное обеспечение и обновления». Я пытаюсь установить CUDA, используя этот метод.

Это вывод терминала при попытке установить cuda через apt:

$ sudo apt-get install cuda  
Reading package lists... Done

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:  
 cuda : Depends: cuda-7-5 (= 7.5-18) but it is not going to be installed  
E: Unable to correct problems, you have held broken packages.

Это то, что я получаю, используя Aptitude:

$ sudo aptitude install cuda

Я не полный фанат Linux, но я довольно удобен в терминале и готов учиться. Это не очень актуальная проблема, но любая помощь будет оценена.
