Почему medibuntu.org по-прежнему предлагается в качестве источника пакета, если он был отключен с 2010 года?

При попытке обновления мой вывод показал, что «Некоторые файлы индексов не загружались» и «Они были проигнорированы или использовались старые». Я что-то неправильно сконфигурировал, или есть причина, по которой mediubuntu.org все еще включен в список, если он был отключен? Вот мое обновление:

Мне удалось удалить это из списка моих источников, следующих за ответом на этот пост: Как удалить сломанный источник программного обеспечения? Это последний измененный wiki октябрь 2013, объясняющий, что он был выключен: https://help.ubuntu.com/community/Medibuntu

Еще раз, я просто хочу облегчить путаницу для новичков / новичков в Ubuntu, как и я, и продвигать хорошие методы обеспечения безопасности. [ ! d7]
