ERROR while installation of nagios xi

[andriconda]

I am new to Nagios. I am following the Nagios: Manually installing Nagios XI video to install Nagios XI on my RedHat Enterprise Linux(RHEL) version 7.2 which is running on an EC2 instance(video link- https://www.youtube.com/watch?time_cont ... BWA6t6dJ4I)
But I am getting an error as-

===================
INSTALLATION ERROR!
===================
Installation step failed - exiting.
Check for error messages in the install log (install.log).

If you require assistance in resolving the issue, please include install.log
in your communications with Nagios XI technical support.

The script that failed was: './1-prereqs'


I have searched for the solution on nagios forum but the workaround mentioned have been tried but it is not working. Could anyone provide a solution to this error.

Are you able to share the contents of the install.log file mentioned in the fullinstall script's output?
