Hi @sushmamagesh, unfortunately reporting errors aren't great at the moment. Kibana 7.5 will be released soon and contains a fix to improve these messages. Until then, there is a troubleshooting guide in the docs you can look at. If you search that page for "CentOS" you'll find some info on dependencies that may be missing in your current installation.
