I recently had to install MySQL 5.6 on Ubuntu 12.04 from a .deb package on the MySQL website.  It seems that either the package has been updated recently or nobody uses this method to install so I ended up running into endless problems.  Through trial and error I found the following method works for me.

Install libaio-dev:
  sudo apt-get install libaio-dev

Now install your package(mine was enterprise edition, community may have a different filename):
  sudo dpkg -i mysql-advanced-5.6.10-debian6.0-x86_64.deb

This will install your files to the /opt directory, instead of the more common /etc directory.  No worries, all we need to do is point our system at this new directory.
