Issue/Introduction

We are installing EM on AWS EC2 RHEL instance. 

The install is being performed with sudo.

The EM install went fine but Postgres install fails with error:

Unable to create symbolic link /tmp/postgresql_installer_c0d3ab958d/lib/./libpgtypes.so -> libpgtypes.so.3.7


Environment

Release : 10.7

Component : APM Database

Resolution

We have found the real cause of this problem is the OS version. 

As a default, AWS now selects RHEL 8.0 for operating system and this in not supported. 

We created the instance again with RHEL-7.6 and installation went good.
