Not good. Sagemath upstream has been working on converting to python 3 for about 5 years now (see https://trac.sagemath.org/ticket/15530), and they are not done. For now, sagemath must remain a python 2 package. Honestly, given how much work upstream still has to do, I do not expect the python 3 version of sagemath to be ready any sooner than a year from now, and quite possibly not until 2 years from now. I've been meaning to post about this. What do we, as a distribution, want to do? As I see it, we really only have 2 options. Option 1. Tell Fedora users that sagemath will not be available for a few Fedora releases, until upstream completes the conversion to python 3. Option 2. Keep all of the python 2 packages that sagemath needs in the distribution until the python 3 version is ready, which possibly means that they have to be kept through Fedora 32. These are the immediate dependencies of sagemath. I haven't gotten around to computing the transitive closure yet. Maybe somebody has a script that can do that. pynac python2-brial python2-configparser python2-crypto python2-cryptominisat python2-cvxopt python2-cypari2 python2-cysignals python2-Cython python2-docutils python2-flask-autoindex python2-flask-babel python2-flask-openid python2-flask-silk python2-fpylll python2-future python2-gmpy2 python2-html5lib python2-imagesize python2-ipykernel python2-ipython python2-matplotlib python2-networkx python2-notebook python2-pathlib2 python2-pexpect python2-pickleshare python2-pillow python2-prompt_toolkit python2-pkgconfig python2-psutil python2-ptyprocess python2-scipy python2-send2trash python2-setuptools python2-six python2-speaklater python2-sphinx python2-sympy python2-twisted python2-ZODB3 rpy scons >From time to time it is necessary to use the bundled version of ipython, because Fedora gets too far ahead and the sagemath code can't cope with the Fedora version. In that case, the dependencies of ipython not listed above are needed: python2-backports-shutil_get_terminal_size python2-path python2-simplegeneric python2-zmq I prefer option 1, of course, but I recognize that that puts a burden on other packagers.
