Now search for MySQL 8.0 using apt cache as shown below:
### Ubuntu 22.04 ###
$ apt-cache policy mysql-server
500 http://ke.archive.ubuntu.com/ubuntu jammy-updates/main amd64 Packages
500 http://ke.archive.ubuntu.com/ubuntu jammy-updates/main i386 Packages

### Ubuntu 20.04 ###
$ sudo apt-cache policy mysql-server
500 http://repo.mysql.com/apt/ubuntu focal/mysql-8.0 amd64 Packages
Step 3: Install MySQL 8.0 on Ubuntu22.04|20.04
sudo apt install mysql-client mysql-server
Having found MySQL 8.0 in our system, we are going to install MySQL 8.0 client, MySQL 8.0 server with the below command:
sudo apt install mysql-client mysql-community-server mysql-server
Hit the y key to start the installation:
Need to get 35.3 MB of archives.
After this operation, 311 MB of additional disk space will be used.

Set a strong password for root MySQL user
Confirm root password by typing it again.
Set default authentication plugin. Use Strong Password Encryption mechanism.
Step 4: Secure MySQL Installation
Run the command below to secure MySQL Server installed onon Ubuntu20.04/22.04:
Press Enter. When prompted for password, provide the root password set above
Enter current password for root (enter for none):
VALIDATE PASSWORD PLUGIN can be used to test passwords
and improve security. It checks the strength of password
and allows the users to set only those passwords which are
secure enough. Would you like to setup VALIDATE PASSWORD plugin?
Press y|Y for Yes, any other key for No: Y
There are three levels of password validation policy:
LOW Length >= 8

STRONG Length >= 8, numeric, mixed case, special characters and dictionary file
Please enter 0 = LOW, 1 = MEDIUM and 2 = STRONG: 1
Using existing password for root.
Estimated strength of the password: 25
Change the password for root ? ((Press y|Y for Yes, any other key for No) : n
Remove anonymous users? [Y/n] Y
Disallow root login remotely? [Y/n] Y
Remove test database and access to it? [Y/n] Y

Thanks for using MariaDB!
Step 5) Validate MySQL 8.0 Installation
Connect to MySQL to check MySQL installed version. To connect to MySQL, run the below command:
$ mysql -u root -p

Creating MySQL Database and User (Optional)
While still connected to MySQL, you can run the following commands to create a database and grant user the permissions.
CREATE DATABASE mydb;
CREATE USER 'mydbuser'@'%' IDENTIFIED BY 'DBUserStr0ngPassw0d.';
GRANT ALL PRIVILEGES ON mydb.* TO 'mydbuser'@'%';
Step 6: Enabling MySQL remote access (Optional)
By default, MySQL remote access is disabled. To enable it we need to edit
mysqld.cnf file as below:
sudo vim /etc/mysql/mysql.conf.d/mysqld.cnf
Look for the line ‘bind_address’ and change as below:
# By default we only accept connections from localhost
#bind-address = 127.0.0.1
bind-address = 0.0.0.0
Save the file and restart mysql
sudo systemctl restart mysql
Allow remote connections through the firewall
sudo ufw allow from to any port 3306
sudo ufw enable
To access the database from a remote machine, run the following command:
$ mysql -u user -h database_server_ip -p
