Problema

Falta una lista de permitidos o el firmante del paquete no coincide con ningún firmante de la lista. El repositorio podría enviar esta lista o especificarla en la sección trustedSigners de nuget.config.

Solución

Si está en modo require, solo los paquetes firmados por un firmante de confianza pasarán la validación. De lo contrario, póngase en contacto con el repositorio desde el que se descargó para informarles de que tienen un paquete que no cumple las directrices de seguridad de firma del repositorio.
