How to reset or delete or enter new password or see the password. If still unable to resolve, how to delete all MySQL dependency and reinstall fresh. I am new to Linux and this is my personal computer (laptop). Please see the output of my terminal.

i suggest steps to reset root password by running the server with option --skip-grant-tables this option allow you to log in in mysql without password running this with sudo:

# sudo service mysql stop

# sudo mysqld_safe --skip-grant-tables &

# sudo mysql -u root

mysql> use mysql;

mysql> update user set authentication_string=PASSWORD("YOUR-NEW-ROOT-PASSWORD") where User='root';

mysql> flush privileges;

mysql> quit

# sudo service mysql stop

# sudo service mysql start

# sudo mysql -u root -p

Now you can login to sql with your new password

check may be it's possible to find a query file about root password in path /home/$USER/.mysql_history or /root/.mysql_history

Note: prior to MySQL 5.7 the column was called password instead of authentication_string. Replace the line above with

mysql> update user set password=PASSWORD("YOUR-NEW-ROOT-PASSWORD") where User='root';

Goodluck
