Environment:
All releases of Spectrum being installed on Linux Platform
Cause:

The hostname does not resolve to localhost and IP Address 

Resolution:

-> Run the below commands to find out the IP Address and the hostname of the server respectively: 

ifconfig

hostname 

-> Now, take backup of the /etc/hosts file and edit it as follows: 

 

127.0.0.1 localhost localhost.localdomain <IP Address> <hostname> 

::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 

 

For e.g. if the IP Address and the hostname is 192.168.10.91 and testserver respectively, the /etc/hosts file needs to be edited as follows: 

 

127.0.0.1 localhost localhost.localdomain 192.168.10.91 testserver 

::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 

 

-> Now, proceed with the installation, should the issue re-occur, restart the server and try the installation again.
