New comment by ericonr on void-packages repository https://github.com/void-linux/void-packages/pull/27872#issuecomment-759153790 Comment: Can you try to fix the tests? Might be a matter of adding `python3-yaml` to `depends` (also anything missing from `install_requires` line in https://github.com/buzz/volctl/blob/master/setup.py) + adding `checkdepends="$depends"`
