To install MariaDB 10.4 on Ubuntu 18.04 / Ubuntu 16.04, you need to add MariaDB repository on to the system.

Step 1: Install software-properties-common if missing:

sudo apt update
sudo apt install software-properties-common

Step 2: Import MariaDB gpg key

Run the command below to add Repository Key to the system

sudo apt-key adv --recv-keys --keyserver hkp://keyserver.ubuntu.com:80 0xF1656F24C74CD1D8

Step 3: Add the apt repository

Once the PGP key is imported, proceed to add repository URL:

sudo add-apt-repository "deb [arch=amd64,arm64,ppc64el] http://mariadb.mirror.liquidtelecom.com/repo/10.4/ubuntu $(lsb_release -cs) main"

If you don’t have add-apt-repository present in your system. check  How to Install add-apt-repository on Debian / Ubuntu 18.04/16.04

Step 4: Install MariaDB Server

The last step is the installation of MariaDB Server:

sudo apt update
sudo apt -y install mariadb-server mariadb-client

You will be prompted to provide MariaDB root password, type the password to set.

Confirm password:

Press <Ok> to confirm the new password and install MariaDB. Make sure you memorize or keep provided password on your favorite password manager.

If you didn’t receive password set prompt, then manually run the MySQL hardening script.

$ sudo mysql_secure_installation 


In order to log into MariaDB to secure it, we'll need the current
password for the root user. If you've just installed MariaDB, and
haven't set the root password yet, you should just press enter here.

Enter current password for root (enter for none): 
OK, successfully used password, moving on...

Setting the root password or using the unix_socket ensures that nobody
can log into the MariaDB root user without the proper authorisation.

You already have your root account protected, so you can safely answer 'n'.

Switch to unix_socket authentication [Y/n] y
Enabled successfully!
Reloading privilege tables..
 ... Success!

You already have your root account protected, so you can safely answer 'n'.

Change the root password? [Y/n] y
New password: 
Re-enter new password: 
Password updated successfully!
Reloading privilege tables..
 ... Success!

By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them.  This is intended only for testing, and to make the installation
go a bit smoother.  You should remove them before moving into a
production environment.

Remove anonymous users? [Y/n] y
 ... Success!

Normally, root should only be allowed to connect from 'localhost'.  This
ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] y
 ... Success!

By default, MariaDB comes with a database named 'test' that anyone can
access.  This is also intended only for testing, and should be removed
before moving into a production environment.

Remove test database and access to it? [Y/n] y
 - Dropping test database...
 ... Success!
 - Removing privileges on test database...
 ... Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n] y
 ... Success!

Cleaning up...

All done!  If you've completed all of the above steps, your MariaDB
installation should now be secure.

Thanks for using MariaDB!

The service should be started automatically after installation.
