We believe this installation is heavily modified from the Ubuntu defaults and that the problem you are experiencing is a result of those changes. For example, the mysql config file is not /etc/my.cnf, but /etc/mysql/my.cnf, and so on (there are other changes).
I suggest you revert your changes, or start over from scratch. In the meantime, this but will be marked as invalid. If you believe what you have is really a bug, then please change the status back to "new" and explain why you think that is the case.
