This seems to be a docker related problem with database access. I often get this question but never received an answer, so: A) You just created an empty metadata.db file B) Your metadata.db file is something else than a calibre library file C) You can't access the metadata.db file or don't have proper permissions D) Something went wrong with "linking" to the metadata.db file outside the docker container
