Hello,
I just set up a new fedora (release 27) and installed sage math using the dnf package manager. in order to start sage I had to install ipython (some dependencies) and, there are also seem to be some packages missing to solve mixed integer programs... I managed to change the error message by installing some further packages but at some point just downloaded the full tar.bz2 from the sage website, which works without any problems
however, since this seems to be a dependency problem please take a look or forward to the responsible developers
Best regards,
Manfred
