Установка пакетов с ubuntu software center.

[truefail]

При скачивании пакетов возникает ошибка: "Failed to download repository information. Check your Internet connection." Хотя с подключением всё в  порядке. Думаю, что вся проблема с содержимым /etc/apt/sources.list

Ubuntu Restricted Extras
Ситуация проясняется. Судя по сообщениям скорее всего проблема в настройках прокси. Сначала вписал прокси, но потом сразу же удалил.  Видимо, они так и остались, но как их удалить, я не знаю.

p.s. Проблема решена обычной перезагрузкой.
