As you may know, Blender is a powerful suite for animation, modeling, interactive creation, post-production with support for a lot of file formats.
The latest version available is Blender 2.77, which has been recently released, coming with a bunch of changes only.
The latest Blender versions are available via some third party PPA, so installing the software on Ubuntu is piece of cake. Just add the PPA to your system, update the local repository index and install the blender package:
$ sudo add-apt-repository ppa:thomas-schiex/blender
$ sudo apt-get update
$ sudo apt-get install blender
Optional, to remove blender, do:
$ sudo apt-get remove blender
The installation instructions should work on Ubuntu 16.04 Xenial Xerus, Ubuntu 15.10 Wily Werewolf, Ubuntu 14.04 Trusty Tahr and derivative systems like Linux Mint 17.x, Elementary OS 0.3 Freya and other Ubuntu and derivative systems.
