I use ubuntu 10.10 which is open source and see it had a MAC OS download, but ubuntu is not the same. Is there a download version for ubuntu?
Unity Technologies still do not provide a Unity Editor for Linux, but it can still be run on Linux using Wine. See the community set up wiki page - http://wiki.unity3d.com/index.php/Running_Unity_on_Linux_through_Wine
Otherwise you may set up a Mac or Windows “Virtual Machine” on Linux to run the Unity Editor.
No, there is no Linux version of Unity. You can run it natively on OS X or Windows; it may or may not run in WINE.
Unity Technologies should build a Debian version of Unity3D.
Where can i find an ubuntu version?
