Мне не хватает 32-битных библиотек: libc.so.6

Я новичок в Linux. Я вчера установил Ubuntu 14.04 64bit на свой MacBook Pro 11,3. Я не знаю, что я сделал неправильно, но я всегда получаю эту ошибку libc.so.6, когда пытаюсь открыть Steam. Я пробовал много решений на форумах Linux и AskUbuntu, но мне кажется, что это работает.

Спасибо за ваше время.

Когда я нажимаю на значок Steam, я получаю этот всплывающий терминал:

Steam needs to install these additional packages: 
libgl1-mesa-dri:i386, libgl1-mesa-glx:i386

Я запускаю эту команду, вводя свой пароль sudo и получаю:

libc6 is already the newest version.
