After trying lots of things  this is what worked for me   sudo mysql -u root ALTER USER  root   localhost  IDENTIFIED WITH mysql native password BY  newpassword      So first we use sudo to log in mysql as root without needing a password  Then we just update root s password   After that  I restarted mysqld   sudo service mysql restart   And the newpassword logged root in
