Не получается установить MySQL в Ubuntu 20.04

После установки mysql (командой sudo apt install mysql-server) я запустил mysql через команду sudo mysql, и выдалась такая ошибка:

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

Я запустил команду sudo apt remove mysql-server, и выдалась уже другая ошибка:

Как это можно решить?
