Issue/Introduction

I am trying to install DR 24.3.1 on a new SLES15 server.

Validate script passes but during installation script I get the following error:

Environment

any supported Performance Management release 

Cause

various environment issues

Resolution

To understand what is causing the issue, check in the Vertica install.log located under /opt/vertica/log

One of the root cause:
I found that the problem was a closed connection when trying to scp the rpm files to the other servers because of disabled or misconfigured sftp between the servers. After fixing that the installation went through.
