I have recently installed Ubuntu-Studio. After install I executed the command:
sudo apt-get update
I also executed this menu item:
System => Software Updater
In spite of this I found the Blender installation I have, which is the one that comes with Ubuntu-Studio, is version 2.76b. But according to the Blender website: https://www.blender.org/download/ the latest stable version is 2.77a. The web page does say this is a "release candidate". On the other hand there is no download on this page that seems to be an actual release and not a candidate release. And given that this web page shows version 2.78 to be the current test build, I have to conclude that 2.77a is the latest stable release. So what is the proper way to get Ubuntu-Studio to update to this latest stable release as given on that download webpage?
