MySql не установлен должным образом, и теперь я не могу использовать центр программного обеспечения или удалить MySql

Когда я открывал центр программного обеспечения, я получил сообщение об ошибке:

«Новое программное обеспечение не может быть установлено, потому что есть проблема с установленным программным обеспечением. Вы хотите исправить эту проблему сейчас?»

, когда я нажимаю кнопку восстановления, я получаю всплывающее окно с сообщением «Операция пакета не удалась. Установка или удаление пакета программного обеспечения не удалась».
