Research direction

Inspect the Python section of the Dockerfile and reproduce the failing scancode-license-data --path command during the Docker build. Check the installed ScanCode command and version, then verify that the build completes and /opt/scancode-license-data contains the intended .LICENSE files without the removed files or static directory.

Description

While running OSS Review Toolkit (ORT) with: docker build -t ort .

[pythonbuild 4/6] RUN scancode-license-data --path /opt/scancode-license-data:

I'm on mac using arm64, and I modified the dockerfile slightly, to get past some other errors like : missing libicu-dev, pkg-config and python3-distutils. I also messed around with changing the python version as well as the scancode version...

The method of dumping the licenses does not seem to work? I've tried almost everything and I am out of ideas. Please save me!

Where in code?
In ORT's source code, the Dockerfile contains information on the build, in the Dockerfile (under the Python section):
Scancode extract license ...
