I want to completely remove MySQL from my system, including databases, settings, logs, journals, etc.
How can I do it?
Update/Note: The MySQL was installed using the following terminal commands:
sudo apt update
sudo apt install mysql-server
sudo mysql_secure_installation
OS Name: Ubuntu 20.04.1 LTS
OS Mode: Live USB drive with persistent storage
MySQL version: mysql Ver 8.0.20

As you already know how you installed it and what version you're working with, you can do the following:
Stop the MySQL service:
Purge MySQL, databases, and configurations:
Remove any additional database files:
The folder where the configuration was and any stranglers:
Clean the logs:
Delete the user-generated during installation:
Finally, get rid of the usergroup that was created during installation:
That should get rid of everything. If you installed a third-party PPA in order to install MySQL then you'll need to remove that.
And that should be everything related to MySQL and nothing else.
