Testcase

Steps to reproduce

Push a branch with prefix proposed-updates, which will automatically trigger a CI pipeline with license scan.

Expected result

The scan process ends with a summary of the licenses used by every file in the package.

Actual result

The scan process ends abnormally with the following trace

Will not fail on change
Will not fail on files with unknown license found

Reproducibility

How often the issue is hit when repeating the test and changing nothing (same device, same image, etc.)?

Put the ✅ in the most appropriate entry:

1. ✅ always
2. often, but not always
3. rarely

Impact of bug

This bug prevents license scan to be run for package texlive-extra which has low impact since it is not in target. However this same issue could be found in other packages.

Attachments

Root cause

The root cause seems to in an upstream bug triggered by licensecheck trying to extract copyright information.
