ERROR certificate-manager 'lstool get' failed: 1

The other day I had to replace the machine SSL certificate on a vCenter Server Appliance 6.5. Since vCenter 6.0 the process of replacing a certificate has been greatly simplified, the certificate-manager script basically takes care of everything which is really nice.
