Running into issue where it is saying the tar file is not really gzipped?
[root]# tar -xvf opensearch-dashboards-2.16.0-linux-x64.tar.gz
gzip: stdin: not in gzip format
tar: Child returned status 1
tar: Error is not recoverable: exiting now
Checking the file shows it as not gzipped.
[root]# file opensearch-dashboards-2.16.0-linux-x64.tar.gz
opensearch-dashboards-2.16.0-linux-x64.tar.gz: data
Running it to unpack normal tar is not doing anything. I copied the contents over to a non-gzipped name file format as it is really a data file. The below runs fine but produces no results.
[root]# tar -xf opensearch-dashboards-2.16.0-linux-x64.tar
