Как избавиться от этого сообщения о неудачной установке [закрыто]

Я установил Ubuntu 11 после его окончания. Затем я попытался установить java из репозиториев. Однако установка не удалась. С тех пор каждый раз, когда я устанавливаю какой-либо другой пакет, apt-get пытается снова установить java, но терпит неудачу и выводит журнал ниже. Я установил Java 8 вручную, поэтому мне не нужно устанавливать java из репозиториев. Мне просто нужно, чтобы это сообщение об ошибке исчезло.
