Сбой обновления до 16.04. Система говорит о нестабильных репозиториях. Получение дубликатов сообщений пакетов во время обновлений [дублировать]

Когда я попытался обновиться до 16.04, он сказал мне, что в моей системе были «неустойчивые пакеты», которые мне нужно было восстановить. Всякий раз, когда я запускаю обновление, я получаю следующее:
