Hi
To Install mysql-server-5.6 I used following commands

sudo apt-get -y remove mysql-server
sudo apt-get -y autoremove
sudo apt-get -y install software-properties-common
sudo add-apt-repository -y ppa:ondrej/mysql-5.6
sudo apt-get -y update
sudo apt-get -y install mysql-server

while Install it following error message is apeared

==> default: dpkg: error processing package mysql-server-5.6 (--configure):
==> default:  subprocess installed post-installation script returned error exit status 255
==> default: dpkg: dependency problems prevent configuration of mysql-server:
==> default:  mysql-server depends on mysql-server-5.6; however:
==> default:   Package mysql-server-5.6 is not configured yet.
==> default: dpkg: error processing package mysql-server (--configure):
==> default:  dependency problems - leaving unconfigured
==> default: No apport report written because the error message indicates its a followup error from a previous failure.
==> default: Errors were encountered while processing:
==> default:  mysql-server-5.6
==> default:  mysql-server

What is the reson for this and how I can install mysql 5.6 .
sudo apt-get -y install mysql-server-5.6 also not working
