I want to install MySQL-8 on Ubuntu-16.04 and I am following official documentation. I haven't installed MySQL on this server in past so this one is the first installation of MySQL.
First, I've downloaded mysql-apt-config using wget just like this:
root@test-server:~# wget https://dev.mysql.com/get/mysql-apt-config_0.8.10-1_all.deb
Then, I updated repositories using sudo apt-get update and then I configured mysql-community-server using dpkg -i mysql-apt-config_0.8.10-1_all.deb and selected the version I want to install (mysql-8).
Then I tried to install MySQL server using apt just like this:
root@test-server:~# sudo apt-get install mysql-server -y
It asked me for root password and I entered it but then, It is showing me following error.

It says that mysql-community-server isn't configured but I already configured it before. I tried re-installing operating system multiple time and also tried installing MySQL 8 using different methods but it's throwing me the same error every time.
