I've completed my Linux Small Business Developer Server installation script. If you have a small team of people that needs a code repository, bug tracking, project management, code review etc,.. then grab a vanilla install of ubuntu 12.10 x64 and run this installation.
More details here.

Free, open source, MIT licensed, no ads, no tracking. Copyrights of installed software may vary.
The only thing I ask, is that you star the project if you like it! That's the only way I'll know if it has been of use to anyone aside from myself.
