While Ubuntu repositories provide an old Blender version, you can always follow this tutorial to install the latest release from the official package. Tested in Ubuntu 14.10, Ubuntu 14.04 and it should work in Ubuntu 10.04 and higher.
Blender is a professional free and open-source 3D computer graphics software product used for creating animated films, visual effects, art, 3D printed models, interactive 3D applications and video games.
So far the latest stable release is Blender 2.72b, which was released a week ago. See the new features in its website.
While Blender in Ubuntu Software Center is old and there’s no PPA repository that always provides the latest binaries, follow the steps below to install the latest release with new features and bug fixes:
Thanks to Thomas Schiex, he is maintaining a PPA that contains the most recent Blender packages for all current Ubuntu releases, though there may be a small delay before the new release made into PPA.
To add the PPA and install Blender, run below commands one by one:
2. Download Blender for GNU/Linux from the official link below. You may first check your OS type, 32-bit or 64-bit, by clicking on “About This computer” from shutdown menu (top-right corner gear button).
3. – a). For single use – If you have only one user on the Ubuntu system, just extract the package to user Downloads folder and run the executable from the result folder:
3. – b). To make all users to be able to run the blender release, extract the package to /opt/ directory.
To do so, press Ctrl+Alt+T to open terminal, run command below to open your Downloads folder as root/administrator:
gksudo nautilus ~/Downloads
Install gksu from Ubuntu Software Center if need. Type in your user password when it asks.
When the folder opens, do:
Right click on Blender package and select open with Archive Manager.
When Archive Manager opens, select Extract to computer -> /opt/
When done, you should see the blender folder under /opt/. For shot, I’ve rename it from “blender-2.72b-linux-glibc211-x86_64” to “blender”.
4. Create a launcher for Blender so that we can start it from the Unity Dash or App Menu.
Press Ctrl+Alt+T to open terminal. When it opens, run command to create .desktop file and edit it with Gedit text editor:
When the file opens, paste below into it and save.

Depends on step 3, you may replace path to Exec & Icon (words in red).
When done, you should be able to open Blender from the Unity Dash or App Menu. Enjoy!
