apt-get remove <пакет> устанавливает альтернативный пакет

Забавно, что всякий раз, когда я пытаюсь удалить пакет с помощью apt-get в Ubuntu 11.04, apt-get пытается установить альтернативный пакет в дополнение к удалению запрошенных пакетов. Вот пара примеров:

Вот вывод --version

Есть какая-то неясная конфигурация или известная ошибка, которая вызывает это?

(Я знаю, что 11.04 отвратительно стар, но я не могу позволить себе роскошь обновлять dist в этом случае.)
