How to completely uninstall Blender?

Question

I installed Blender 2.79, but I want to install Blender 2.80. How can I uninstall it?

Answer 1

If you installed from snap, run:

sudo snap remove blender

If you installed from PPA, run:

sudo apt-get remove --autoremove blender

Edit: if you installed in /opt as you describe, run:

sudo rm -rf /opt/blender

When you install 2.8, you may wish to install with a package manager so it automatically updates:

sudo add-apt-repository ppa:thomas-schiex/blender
sudo apt-get update
sudo apt-get install blender

Answer 2

If you installed Blender like that:

tar -xjf blender--x86_64.tar.bz2
sudo mkdir /opt/blender
sudo cp -r blender--x86_64/* /opt/blender

Then you can just move the old version into an other directory:

sudo mv /opt/blender ~/blender_279

Then you can install the beta version via snap, so you get automatically the newest blender versions:

sudo snap install blender --beta

If you want to download and install blender by hand, you can still use your old method and download the new one: https://builder.blender.org/download/ and repeat the installation (extraction and copy the files to /opt/blender)
