dnf install ptyhon3.13 You just need to find a way to tell sage to use python3.13 and not python3.14. There must be a way for that, but I don't know it.
Incidentally, on Fedora 42 there is already the problem that sage doesn't build on gcc15, so you need to install gcc14 and tell sage to build with that; see https://groups.google.com/g/sage-devel/c/tJCbTnelvSg/m/IfzQF0HGBQAJ . I would imagine you'll need to do that on Fedora 43 as well, until gcc15 is fully supported for building sage.
