Проблемы с установкой MongoDB в Linux Ubuntu 20.04

. Другие задавали этот вопрос, но я не нашел ответа, который работал бы для меня. Я пытаюсь установить MongoDB на Ubuntu 20.04. Я следил за руководством по адресу https://docs.mongodb.com/manual/tutorial/install-mongodb-on-ubuntu/ , но во время установки столкнулся с проблемами. Во время установки возникает ошибка (первая ошибка ниже), затем я проверяю, что установка сработала с помощью команды --version, кажется, она установлена, я пытаюсь запустить и получаю последующий сбой (mongod.service не найден).

Затем я снова попытался дважды проверить, чтобы удалить предыдущие файлы, следуя совету Cool Kev ниже. Вот полная распечатка новой установки и ошибок:
