DistroWatch reports - The Ubuntu, Kubuntu and Edubuntu teams are proud to present a second beta release of Ubuntu / Kubuntu / Edubuntu 6.06 LTS, codenamed 'Dapper Drake'. This release corrects some serious flaws in the installer present on the Desktop CD in the first beta release. Although the text-mode install CD also forms part of this release, it has not been modified since Beta 1.

OSDir had a look at the changes since the previous Dapper beta in the Ubuntu 6.06 Beta 2 Screenshot Tour.
