apt-get -y autoremove

I found an error when I execute the script on RPI3:
It may could be changed from as following 2 lines:
sed -i 's/^bind-address/#bind-address/' /etc/mysql/mysql.conf.d/mysqld.cnf
sed -i 's/^skip-networking/#skip-networking/' /etc/mysql/mysql.conf.d/mysqld.cnf
To:
sed -i 's/^bind-address/#bind-address/' /etc/mysql/mariadb.conf.d/50-server.cnf
sed -i 's/^skip-networking/#skip-networking/' /etc/mysql/mariadb.conf.d/50-server.cnf
And save as the new script.

thank you very much!
After an update from ¨raspberry jessie¨ mpa did not work properly anymore.A fresh image did all I needed and this script worked flawlessly!
great
