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
Release : 10.7
Component : APM Database
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.
