I did not manage to install mysql on Ubuntu completely

Question

I did not manage to install mysql on Ubuntu completely...

I encountered a strange problem when installing mysql!

When I entered this command in the Ubuntu terminal, I encountered the following error to install mysql:

sudo apt install mysql-server

Of course, before this, I completely deleted mysql once with the following command:

sudo apt-get remove --purge mysql*

And

sudo apt-get purge mysql*

And

sudo apt-get remove dbconfig-mysql

After importing these commands, I decided to install mysql again from the first, so I entered the following command:

sudo apt-get install mysql-server

I then saw the following error message inside the terminal:

This installation of MySQL is already upgraded to 5.7.27, use --force if you still need to run mysql_upgrade Job for mysql.service failed because the control process exited with error code. See "systemctl status mysql.service" and "journalctl -xe" for details. invoke-rc.d: initscript mysql, action "start" failed.`
