"_extract_tar: skipping link with missing target:" in the docker pipeline

[pombredanne]

While scanning docker://quay.io/wire/alpine-deps I get this :

_extract_tar: skipping link with missing target: <TarInfo 'bin/arch' at 0x7ffa99193d00>: Traceback (most recent call last):

@pombredanne @JonoYang should we create an issue on the container_inspector side then?

[pombredanne]

@tdruez if we were to treat and report these are warnings or info rather than errors, would there be a way to display these as such in the UI rather than as errors?

[tdruez]

We would have to refactor the "Error" system into a more global "Message" model with a new level type: info, warning, errors.
That would be a good improvements in any case, but this would not solve the actual extraction issues.
