I used several custom registries for services and now I cannot install any services from these registries. How to trust these services explained simply.

Hi

You would have to ask admins of this registry who host them. If you are asking how to add custom registry then you just go to Marketplce \> Choose registry \> add

Beginning with StartOS version 0.4.1, to increase security, users are allowed to select who (by their digital signatures) they trust for installation of services and OS.

See: [Trusted Keyrings - StartOS](https://docs.start9.com/start-os/0.4.1.x/trusted-keys.html)

Services are signed by the author / maintainer. You can add the public key of the maintainers you trust to your trusted keyring in StartOS. Then any services they sign will be allowed to be installed. You should be able to reach out to the owners of those custom registries and ask for their help too.
