How to install Blender 2.92 released on Ubuntu 20.04, 20.10 via PPA

 Blender is the free and open source 3D creation suite. It supports the entirety of the 3D pipeline—modeling, rigging, animation, simulation, rendering, compositing and motion tracking, even video editing and game creation.


Blender 2.92  highlights:

  • Multithreaded export of geometry, to improves performance in scene synchronization when there are many mesh, hair and volume objects.
  • GPU devices can now take over tiles that are currently being rendered by CPU threads to improve hybrid rendering performance.
  • NVIDIA OptiX
    • Hybrid rendering with CPU and GPU devices is now supported.
    • AO and Bevel shader nodes are now supported.
    • NVIDIA driver version must be 450 or newer, due to an upgrade to OptiX 7.1. This makes it possible to render more object instances.
  • Intel Iris and Xe GPUs can now be enabled for OpenCL rendering
And see the release note for more.

 

Installation instructions:

     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

 
Fix missing libLLVM-6.0.so.1 issue:

Blender 2.92 does not start in my Ubuntu 20.04, and it outputs an error when running from terminal:

    /usr/lib/blender/blender: error while loading shared libraries: libLLVM-6.0.so.1: cannot open shared object file: No such file or directory

This can be easily fixed by running command:

$ sudo apt-get install libllvm6.0

Optional, to remove Blender , do:

$ sudo apt-get remove blender
