Most CAs have multiple levels of certificates. The ones that the browsers include in trust bundles are normally stored off-line in locked vaults in multiple shards and are only reconstructed once every few years for use, to sign intermediary certificates. The intermediary certificates are the ones that are used to sign end-user certificates. These are not included in the browser bundles. Every site that uses them is expected to include them in their certificate chains. > public verification using this.

The trouble is, browser authors have seen incomplete chains before, and have gone to some efforts to try to remediate the problem themselves. They will *store* intermediate certificates as they discover them around the wider web. If a misconfigured site forgets to include the full chain of certificates, quite often site admins won't even notice because the intermediate certs will be in their *local* user configuration. This is what makes a service like Qualys's TLS checker so wonderful: it's a well-written neutral third-party that knows how to diagnose a suprising number of deployment and implementation mistakes.

The "DigiCert SHA2 Secure Server" was intended. This post has been edited for clarity. ------------- The "DigiCert SHA2 Secure Server" certificate is missing, which means that the system does not trust web sites that are using SSL certificates signed by that root. An example is a popular website in the Netherlands https://marktplaats.nl. The result is that no resources other that the text-only homepage is loaded. Installing the Digicert root certificte manually from Digicert solves the problem: ``` wget https://dl.cacerts.digicert.com/DigiCertSHA2SecureServerCA.crt mv DigiCertSHA2SecureServerCA.crt DigiCertSHA2SecureServerCA.der openssl x509 -inform DER -outform PEM -in DigiCertSHA2SecureServerCA.der -out DigicertSHA2SecureServerCA.pem.crt sudo mkdir -p /usr/share/ca-certificates/extra sudo cp DigicertSHA2SecureServerCA.pem.crt /usr/share/ca-certificates/extra/ sudo dpkg-reconfigure ca-certificates ``` Maybe there is a valid reason for not including this certificate by default, or maybe this certificate can be included by default, since it seems like it's assumed to be included on every machine.
