как завершить обновление с 16.04 до 18.04? [дубликат]

Наконец-то я решил обновить свой настольный компьютер с 16.04 до 18.04.

И, как и ожидалось, все пошло не так гладко. Ну, мой компьютер стал зависать, и я больше не мог его разблокировать после того, как начал обновление (поэтому я оставил его там примерно на 24 часа). А после перезагрузки он просто зависает после экрана входа в систему, переключение на оболочку дает мне:

$ sudo apt update;sudo apt -y upgrade
