  • I purchased an SSL certicate and I have the CA bundle. When I try to verify the certificate, it fails with the error below:

    # openssl verify server.crt
server.crt: C = US, O = Example Inc., CN = Example Inc. CA
error 2 at 2 depth lookup:unable to get issuer certificate

  • How do I add CA certificate to trusted root certificates?

Environment
