I was recently installing mysql in Ubuntu Bionic Beaver and the command ‘UPDATE User SET password…’ does not apply here. Instead, you have to do
UPDATE User SET authentication_string = password(“Mypassword”) where User=’root’;
for the password to be updated.
Thanks for the great post.
One issue. is you have to be logged in as a system root user for all these commands, if not, then use sudo and then the command. i.e. sudo mysqld_safe –skip-grant-tables &
If you are not logged in as a root user, then you will get many issues and not be able to reset your password. Also I would avoid using # or @ in your passwords.
