Affected NV Version: 7.4.x
OS Version: Unix/Linux
Symptom: Unique Seeding Failed, Can't get host name during Install on a Unix client.
This error means that NV is not picking up the Host name of the Client it is being installed on.
From Command prompt type "hostname". You most likely will get an incorrect response back. Once this Networking Configuration problem is resolved then install should complete without error.
As a workaround, add your machine information to the /etc/hosts file
X.X.X.X myhostname.mydomain.org myhostname
