Steps to reproduce the behavior
Fully reproducible environment available as github workflow:
https://github.com/ambianic/ambianic-rpi-image/runs/1405211947?check_suite_focus=true#step:9:4292
Context summary:
The goal is to build a Raspberry Pi OS custom image with docker on it. We are using the official pi-gen project with a custom step that installs docker.
The step seems to succeed in installing docker, but when we try to actually run it we see the reported error message.
Similar problems have been reported before:
