I have been maintaining Flatpak builds of Blender for some time, now. In fact at the time I started Flatpak was still called XDG-App. :)

As of today, my Blender builds are now on Flathub, and I will stop updating my personal repository.

One of the benefits of moving it to Flathub is that it is a shared resource, where others can maintain the app so that it doesn't rely solely on me. Another one is that Blender is now available on i386, x86_64, but also ARM and Aarch64.

You can add the Flathub repository and install Blender from it as follows:

$ flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
$ flatpak install flathub org.blender.Blender

At this point you can run Blender from your favourite graphical environment, or from the command line:

$ flatpak run org.blender.Blender

Don't hesitate to let us know if you encounter any issue with this build which is not an upstream bug. (compare with the upstream bundle)

Note: If you had previously installed Blender from my repository, you'll want to uninstall it first:

$ flatpak uninstall org.blender.Blender
$ flatpak remote-delete bochecha
