Как установить MySQL server на Ubuntu 18.04 bionic на облачном Hetzner сервере

[cegthgtlhj]

Сам я абсолютный нуль в линуксах. Мне нужно установить MySQL server и развернуть на нем Джанго вебсайт.
У меня облачный сервер на Hetzner.de Ubuntu 18.04.4 LTS /// bionic
Начал устанавливать MySQL server, начал по простому

sudo apt update
sudo apt upgrade
sudo apt install mysql-server

Это не сработало.
Перерыл как минимум 10 веток на stackoverflow.com и перепробовал их.
Возвращается та же самая ошибка.

Последняя попытка была использовать эту инструкцию https://ru.stackoverflow.com/questions/992815/%D0%9A%D0%B0%D0%BA-%D1%83%D1%81%D1%82%D0%B0%D0%BD%D0%BE%D0%B2%D0%B8%D1%82%D1%8C-mysql-8-0-8-0-15-%D0%BD%D0%B0-ubuntu-18-04-%D1%82%D0%B0%D0%BA-%D0%B6%D0%B5-%D0%B4%D0%BB%D1%8F-digitalocean

Python удалять не нужно паки dist-packages будет достаточно. В домашнем каталоге тоже можно не удалять

Благодарю вас за поддержку.
Мне подсказали следующее.
Пароль юзера истек - необходимо поменять.
Это видно из сообщения об ошибке, которое я не знал как истолковать.

Сделал как написано здесь - ввел пароли еще раз
