I just installed sagemath 8.0 into my Fedora Linux 64-bit system. It
crashes on start-up.
My version of linux is 4.17.7-200.fc28.x86_64
Installation was by:
sudo dnf install sagemath
I started by clicking on an icon - gnome3 .desktop file looks like:
[Desktop Entry]
Name=Sagemath
Comment=A free open-source mathematics software system
Exec=sage
Icon=sagemath
Terminal=true
Type=Application
Categories=Science;Math;
Crash-report attached
