For Ubuntu 19 with MySQL 8.0.17-0ubuntu2, what ended up working for me was a combination of many answers:

1. In the MySQL's configuration file (/etc/mysql/mysql.conf.d/mysqld.cnf on my machine), under [mysqld], add:

   skip-grant-tables = 1 plugin-load-add = auth_socket.so

2. Restart the MySQL Service;

3. Connect to MySQL: mysql -uroot;

4. Run:

UPDATE mysql.user SET authentication_string=null WHERE User='root';
FLUSH PRIVILEGES;

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'pass123';

5. Stop MySQL and comment skip-grant-tables in the configuration file;

6. Start MySQL again and this should now work: mysql -u root -ppass123.
