It's an image that contains only a single binary that returns 0. That binary uses no libraries, not even libc. It's intended as an extremely light-weight image for purposes that don't need a whole OS. See, for example, https://stackoverflow.com/questions/37120260/configure-docker-compose-override-to-ignore-hide-some-containers It seems that something changed between 19.03.12+dfsg1-3 and 19.03.12+dfsg1-4 that is somehow or other assuming the container contains more infrastructure. If you determine that the bug is upstream, feel free to forward it to them (and, ideally, revert whatever patch was added to 19.03.12+dfsg1-4 that caused the problem in the mean time to avoid breaking other software on the system).
