This pertains to installation of sage-9.7.tar.gz under WSL2. I've found it necessary to run
cp -r $HOME/sage/sage-9.7/src/sage/ext_data/ $HOME/sage/local/lib/sage in order for various packages to pick up code in ext_data. I'm compiling from source. I prefer to configure sage to compile as much as possible and to rely on ubuntu/debian packages as little as possible.
