I just tried to install mysql-server-5.6, it asked for root-password twice and then said it could not set the root password, then dpkg failed to start mysql (invoke-rc.d: initscript mysql, action "start" failed.). Now apt wants to finish the broken mysql-installation everytime i try to use it. When i try to start the mysql server manually (sudo service mysql start), it gives me "start: Job failed to start" and nothing else.

Not a bug, more of an installation support issue.
