Ошибка при установке mysql-сервера - теперь я не могу установить какой-либо пакет
У меня Ubuntu 20.04. MySQL-сервер не удалось установить.
Теперь, когда я запускаю sudo apt install -f , я получаю
$ sudo apt install -f

No apport report written because the error message indicates its a followup error from a previous failure.
Errors were encountered while processing:
mysql-server-8.0
mysql-server
E: Sub-process /usr/bin/dpkg returned an error code (1)
sudo dpkg ––configure –a тоже не работает.
Я не могу установить ни один пакет.
Вопрос отличается от проблема установки mysql-server-8.0 в Ubuntu 20.04 , потому что я абсолютно не могу установить mysql-server. Ему удалось установить его. И мой менеджер пакетов сломался при его установке, поэтому я не могу ничего сейчас установить или удалить.

Загрузите систему в режиме восстановления и запустите dpkg , который должен восстановить поврежденные пакеты.
