The package whose postrm is being called may have previously been deconfigured and only be “Unpacked”, at which point subsequent package changes do not consider its dependencies. Therefore, all postrm actions must only rely on essential packages and must gracefully skip any actions that require the package’s dependencies if those dependencies are unavailable.
