So, you can get the latest package of MySQL server easily from the Ubuntu repository. We have executed all commands on the terminal.
However, you need to open the terminal on your system. Click on Activities and then from the application search bar you can launch it.
You need to implement the following steps to install the latest MySQL package on your Ubuntu system.
1. Update apt repository
It is recommended to update the Ubuntu apt repository on your server before installing any new required package. Therefore, by using the following command you can update the apt repository:
$ sudo apt update
2. Install MySQL server
Once the apt repository is updated, you will install the MySQL server package on your system. To do this, execute the following command on the terminal:
$ sudo apt install mysql-server
The above-given command will install the MySQL server on your system. But, it is recommended to make secure the MySQL server installation.
3. Verify the Installation
After completing the installation of MySQL server, its services will automatically start on your system. To view the status of the running services of MySQL server, you can execute the following command:
$ sudo systemctl status mysql
This will ensure that all MySQL services are running on this system.
4. Make secure the MySQL configurations
To make the installation secure, you need to run the security script to make the secure configurations of MySQL server. When you will run the script on your terminal, it will ask to change less secure features such as remote logins for root users. Type the following command to make the configurations more secure:
$ sudo mysql_secure_installation
Here, Press 'y' key from your keyboard to allow the installation of 'Validate password plugin'. This plugin will install and then configure on your system. This is used to test the password strength for MySQL users. It also improves the security level as well.
Three different levels of password validation policy you will see that are low, medium, and strong. You need to select a strong password for MySQL server. Therefore. Choose option '2' for strong password strength. In the next step, it will ask you to enter the password of MySQL for the root user account.

In the next step, it will ask you to confirm the following questions:

c. Remove the test database and access to it?
d. Reload privilege tables now?
You will enter 'y' in order to confirm the all above statements.
