Section Number and Name:

1.2. Prerequisites

Describe the issue:

satellite-maintain upgrade and satellite-installer will fail if any of the CA certificates in the custom CA bundle has SHA1 signed hash. 

Check if server certificate authority is sha1 signed:                 [FAIL]

Suggestions for improvement:

The Prerequisites section for upgrade to 6.16 should mentions the change. 

For example:

Satellite servers no longer supports SHA1 signed CA certificates. Ensure that you replace any affected CA certificate the non-SHA1 signed certificate before initiating the upgrade.
