Leave it here and removing these package on my machine

@frankspace the pkg is installed via your fix.

Thanks @frankspace, I will check this and push update soon.

@fam007e, please test the fix I posted below.

Is this no longer going to work for me as this error is popping up for a few days now:

 -> error making: python-future-exit status 4

The python-fissix package in the official repos provides a drop-in substitute for lib2to3. I am not clever enough to know whether the various SyntaxWarning warnings are important, but this will both compile and pass checks by adding python-fissix as a dependency and adding the following to the PKGBUILD:

prepare() {
  cd "$srcdir"/future-$pkgver
  find . -type f -name "*.*" -exec sed -i 's|lib2to3|fissix|g' {} +
}

I'm not disputing that projects shouldn't be using this anymore, but at least one that I use seems to be abandoned, so getting them to do so may be infeasible. Using fissix seems to work in the meantime.

I don't know why "python-future" is installed by default, but it's now breaking system upgrades so I removed it.

yay -R python-future

I assume pacman etc will work fine with just "python" currently at v3.13.1-1
