Edubuntu 12.04.5 is a new set of live and installation images that include all recent security and bug-fix updates for the project's older LTS (long-term support) release, supported until April 2017. 12.04.5 contains an updated kernel and X stack for new installations on x86 architectures. As usual, this point release includes many updates, and updated installation media has been provided so that fewer updates will need to be downloaded after installation.
About Edubuntu
Edubuntu is a partner project of Ubuntu, a distribution suitable for classroom use. The aim is that an educator with limited technical knowledge and skill will be able to set up a computer lab, or establish an on-line learning environment, in an hour or less, and then administer that environment without having to become a fully-fledged Linux geek.
