This is an Appimage for running SageMath on linux systems which use glibc version 2.17 or later, including virtual systems running in Microsoft WSL on Windows.

Linux Installation

1. Download SageMath-x86_64.AppImage from the assets.
2. Create ~/bin (if necessary): mkdir -p ~/bin
3. Move the AppImage into ~/bin: mv ~/Downloads/SageMath-x86_64.AppImage ~/bin
4. Make it executable: chmod +x ~/bin/SageMath-x86_64.AppImage
5. Create a convenient symlink: ln -s SageMath-x86_64.AppImage ~/bin/sage

You need to have ~/bin in your PATH to run sage conveniently. This should happen automatically, but you may need to log out and log back in if your ~/bin directory did not already exist in step 2.

If you are using a linux desktop system, such as Gnome or KDE, you can add Sage to the desktop application menu and create an icon which can be pinned to the Ubuntu Dash or KDE Taskbar by running the command:
sage --install-desktop
(That command creates ~/.local/share/applications/sagemath.desktop and ~/.local/share/icons/sage_icon.svg.)

Windows WSL2 Installation

The commands listed above should be run in your WSL powershell, except that you should replace step 3 by:
3'. Move the AppImage into ~/bin: mv /mnt/c/Users/<your id>/Downloads/SageMath-x86_64.AppImage ~/bin
(Replace <your id> with your Windows user id.)

Usage
To run sage, open a linux terminal or WSL powershell and typesage or sage -n or sage -n jupyterlab.

Or, on a linux desktop, after pinning the application icon, just click on the icon. This will start the command line version of Sage. You can arrange to launch a notebook by editing the sagemath.desktop file to add -n on the Exec line.

This AppImage includes the python tkinter module, which works in Sage (after running %gui tk) on a linux desktop. It does not work in WSL since it requires an X server.
