• fail to start mysql on Ubuntu 12.04 (Desktop)
• We have to re-install 'mysql-common' package

• "$ sudo aptitude purge mysql-server-5.5 mysql-common"
  • you need to backup your data (/var/lib/mysql/*)
• "$ sudo aptitude install mysql-server-5.5"
  • MySQL fails to start after upgrade to 12.04? - Ask Ubuntu

• on Ubuntu Server 12.04, the mysql-server-5.5 (5.5.22-0ubuntu1) package has broken. I think the latest version (5.5.24) is the same (has broken still).
  • according to this page: Cannot install mysql-server (5.5.22) on clean ubuntu 12.04 LTS server - Ask Ubuntu
  • So We have to make a binary from source code
