Mojca, sorry I missed you query about the location of the image zip. I used: https://downloads.raspberrypi.org/raspios_arm64/images/raspios_arm64-2020-05... But the lite version you mention below should use the same library.

....Does this look like the correct place for fetching the images with Debian 10? https://downloads.raspberrypi.org/raspios_lite_arm64/images/raspios_lite_arm...

Mojca

Regards, Jay p.s. I'm away from the rpi now but will try out the new runtime prog you sent and get back to you. --- END
