See https://getcomposer.org/dep-on-root for details and assistance. - solido/body-converter dev-master requires solido/common ^0.4 -> satisfiable by solido/common[dev-master, v0.4.0, 0.4.x-dev (alias of dev-master)] from composer repo (https://repo.packagist.org) but solido/common dev-renovate/pin-dependencies is the root package and cannot be modified.
