Maybe @iocanel could tell more. But afik that was the conclusion at the end, that is probably something with shading.

@csviri would you mind to elaborate? crd-generator-api is a transitive dependency of crd-generator-apt and, the only reason (I can think about) why a direct dependency would fix something is because of a misconfiguration of the shading. Any other ideas?
