ddwangnz, I had a similar issue on the raspberry pi 4. Had to perform the extraction and mounting of the img on another Ubuntu/linux box (vm or otherwise).
Running this on a raspberry pi fails with an error "failed to add service - already in use?". Based on the FAQ/Support thread over at steam forums, here is what it says
* Running on the console on Debian Buster isn't supported, the graphics device isn't available for EGL context creation. Try running under X11 instead.
