-# Here are the few steps that I have performed to get the `debconf` setting information:
-#
-# - downloaded the mysql-apt-repo from the mysql official site(named: mysql-apt-config_0.6.0-1_all.deb)
-# - Find the `debconf` setting information after installing this `deb` package
-# 
-# # debconf-show mysql-apt-config
-# * mysql-apt-config/select-server: mysql-5.6
-#   mysql-apt-config/unsupported-platform: abort
-#   mysql-apt-config/repo-codename: precise
-# * mysql-apt-config/select-product: Apply
-#   mysql-apt-config/select-tools:
-#   mysql-apt-config/repo-distro: ubuntu
-# 
-# - Even to get more information about the `debconf` options of the package:
-# 
-# # debconf-get-selections|grep mysql-apt-config
-# mysql-apt-config  mysql-apt-config/select-server  select  mysql-5.6
-# mysql-apt-config  mysql-apt-config/unsupported-platform select  abort
-# mysql-apt-config  mysql-apt-config/repo-codename  select  precise
-# mysql-apt-config  mysql-apt-config/select-product select  Apply
-# mysql-apt-config  mysql-apt-config/select-tools select
-# mysql-apt-config  mysql-apt-config/repo-distro  select  ubuntu
-# 
-# - After the installation, I have checked the `/etc/apt/sources.list.d` directory and found one file `mysql.list` 
-# with following contents:
-# 
-# deb http://repo.mysql.com/apt/ubuntu/ precise mysql-apt-config
-# deb http://repo.mysql.com/apt/ubuntu/ precise mysql-5.6
-# deb-src http://repo.mysql.com/apt/ubuntu/ precise mysql-5.6
-# 
-#
-# Thought that instead of performing all those steps and get the repo, why not directly use this repo 
-# `deb http://repo.mysql.com/apt/ubuntu/ precise mysql-5.6`, I just picked this line and directly used it and it worked for us.
