Hi Mahmoud Thanks for taking the time to report this bug in Ubuntu.
I notice from the installer log that you are trying to install mysql- server-5.0. This is not supported on Ubuntu 12.04 as is causing the error that you are seeing. I would recommend that you don't try and mix 5.0 and 5.5. Marking this bug as 'Invalid' as it relates to non-Ubuntu distributed software.
