Comment 15 for bug 973951

Using Theo's suggestion to reinstall apparmor, I was able to do a clean install of MySQL...

# Remove crash information
$ sudo rm /var/crash/*

# Remove previous mysql installation (you will lose your data!)
$ sudo apt-get --yes autoremove --purge mysql-server
$ sudo rm -rf /var/lib/mysql
$ rm -rf ~/.mysql
$ sudo rm -rf /etc/mysql

# Reinstall apparmor
$ sudo apt-get install --reinstall apparmor

# Install MySQL
$ sudo apt-get install mysql-server

If this works for others, we may be able to mark this bug as triaged, but I think there may be an issue (with apparmor?) that needs to be fixed.
