Package error on SuiteCRM 7.11.8

Using SuiteCRM Version 7.11.8, PHP 7.2 and making modules via Module Builder. Once the Package is Published or Exported as a ZIP. This package is used on Server running Ubuntu 16 and PHP 7.2. So uploading the exported/published package on server gives following error.

Strangely the manifest.php file is unzipped to the CRM root, and not in the upload or upgrades folder.

host_name in config.php is
site_url is

Any other place to check why it extracts the manifest to CRM Root Folder?

1: Have you checked .htaccess file? Any issue there?
2: Try setting CRM permissions
