Я не могу запустить mysql.server в Ubuntu 20.04

Версия Ubuntu:

No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 20.04.2 LTS
Release:    20.04
Codename:   focal

У меня проблемы с запуском mysql, всегда, когда я пытаюсь, появляется следующий сообщение:

Job for mysql.service failed because the control process exited with error code.
See "systemctl status mysql.service" and "journalctl -xe" for details.

Я попытался проверить mysqld.log с помощью команды tail -f /var/log/mysqld.log, но, похоже, его нет.

Я попытался проверить с помощью systemctl status mysql.service и получил следующее:

mysql.service - MySQL Community Server
     Loaded: loaded (/lib/systemd/system/mysql.service; disabled; vendor preset: enabled)

Мой файл mysql.cnf настроен следующим образом:

#
# The MySQL database server configuration file.
#
# You can copy this to one of:
# - "/etc/mysql/my.cnf" to set global options,
# - "~/.my.cnf" to set user-specific options.
# 
# One can use all long options that the program supports.
# Run program with --help to get a list of available options and with
# --print-defaults to see which it would actually understand and use.
#
# For explanations see
# http://dev.mysql.com/doc/mysql/en/server-system-variables.html

#
#  IMPORTANT: Additional settings that can override those from this file!
#   The files must end with '.cnf', otherwise they'll be ignored.
#


!includedir /etc/mysql/conf.d/ 
!includedir /etc/mysql/mysql.conf.d/

Далее я попытался установить и после удаления репозитория MySQL APT, но появляется это сообщение:

Error while installing package: the subprocess installed, package mysql-common, script post-installation return the error status exit 2

Вывод команды sudo journalctl -u mysql.service -n 100 :

Команда sudo tail -f / var / log / mysql / error.log ничего не возвращает

Как я могу это исправить?
