Ошибка при обработке пакетов при попытке установить python-pygame

Что бы я ни пытался установить, используя apt-get install, это просто не работает.

Я пользуюсь Elementary OS (на основе Ubuntu) со вчерашнего дня, поэтому я довольно новичок в Linux.

Вот пример моей проблемы:

$ sudo apt-get install python-pygame
