Docker convenience script stuck after "Scanning linux images"

I have a Raspberry Pi 2B and a fresh install of Raspbian.

I am trying to install Docker, and following the instructions on the site (https://docs.docker.com/engine/install/debian/#install-using-the-convenience-script), I used the convenience script just like it's written there.

This is all the output I get:

Scanning linux images...

I let it run for more than a half hour and nothing changes.

How do I resolve this?

Just found this question from 5 days ago because I ran into the same thing on a RPi 4, also using the convenience script.

Just waiting a bit did not seem to help. So I killed the process after a while. And Docker is running just fine, now.
