Не удалось получить http://us.archive.ubuntu.com/ubuntu/dists/lucid/main/source/Sources 404 Не найдено [IP: 91.189.91.26 80]

Я использую Ubuntu 16.04 LTS. Сегодня утром, когда я побежал sudo apt-get update, я столкнулся со следующей ошибкой:

W: The repository 'http://us.archive.ubuntu.com/ubuntu lucid Release' does not have a Release file.
N: Data from such a repository can't be authenticated and is therefore potentially dangerous to use.
N: See apt-secure(8) manpage for repository creation and user configuration details.
E: Failed to fetch http://us.archive.ubuntu.com/ubuntu/dists/lucid/main/source/Sources  404  Not Found [IP: 91.189.91.26 80]
E: Some index files failed to download. They have been ignored, or old ones used instead.

Я проверил интернет для ответа. Хотя я нашел несколько подобных сообщений, ни одно из решений не работает для меня. Одним из интересных решений, которые я пробовал, было:

Самое простое решение состоит в выполнении следующих двух шагов:

1- Резервное копирование списка источников -> sudo cp / etc / apt / sources .list /etc/apt/sources.list.backup

2- Открыть исходный файл «/etc/apt/sources.list» Переименовать все экземпляры us.archive или archive в http://us.archive.ubuntu.com/ubuntu/ до

http://old-releases.ubuntu.com/ubuntu/

Также сделайте то же самое для http://security.ubuntu.com/ubuntu/dists/saucy-security/universe/binary-i386/Packages

3- Запустите sudo apt-get update после выполнения вышеуказанного.

Угадай, что .. не работал.

EDIT:
