Comment 8 for bug 1435081

I wrote the comment below on the duplicate bug here:
https://bugs.launchpad.net/ubuntu/+source/mysql-5.6/+bug/1435080/

I will repost it here if it helps anyone.

Got it fixed - first I followed this:
https://bugs.launchpad.net/ubuntu/+source/mysql-5.6/+bug/1435080/comments/11

It didnt work alone - but after deleting this file:
sudo rm /etc/systemd/system/mysql.service

And :
sudo apt-get purge mysql-server-5.6 mysql-server

I could remove it and then install it again:
sudo apt-get install mysql-server-5.6 mysql-server
