Please try using this command to remove MySQL completely from your current Linux system including your databases, settings and everything else.

sudo apt-get purge mysql

Hopefully I didn't mistyped :p Let me know if it worked for you.

apt automatically installs the latest version available in the added repositories.

to see all the available versions in your enabled repositories, run

apt-cache policy mysql-server

if the version you want to install is not listed in the output, then you might need to add extra repositories.

Coming to 254 not upgraded part, it just means that updates for 254 packages are available in the repositories. You can install those updates using

sudo apt-get upgrade

Try uninstalling it from software manager and restart the system, it worked for me.
