@xantares: In the current version, Natron does not support Python 3:

https://github.com/NatronGitHub/Natron/blob/v2.3.15-rc.7/README.md

does it not support python 3 ? (python2-pyside instead of python-pyside)

@Zeioth: The Natron package and OpenFX dependencies have been updated. The build is working now.

In my experience it's better to install Natron from the portable installation provided by Natron's webpage. Otherwise use flatpak.

Natron AUR packages have a huge number of dependencies that will usually fail to install or update. And take forever to compile.

@FirstAirBender: I updated the PKGBUILD of the openfx-io package.

Thanks for helping!

It was failing to compile for me so I had to make a few changes to one of the dependencies (openfx-io).

After it fails, create the following patch file (from the openfx-io master branch) and place it in the ~/.cache/yay/openfx-io folder:

git diff Natron-2.3.14 > master-patch.diff

Reattempt to build install the package with:

yay --editmenu -S natron

It will offer you the option to edit the PKGBUILD for openfx-io. Replace the PKGBUILD with this one:

Installation with pacaur failed/ends at fetching the necessary packages:

I'm getting a large list of dependencies that need to be installed more than list shown above.

One in particular is Gimp! Surely I don't need to install that as a dependency do I?
