I was told that insights-client cannot be installed in RHEL 10:

- nothing provides /usr/libexec/platform-python needed by insights-client-3.2.2-2.el10.noarch from beaker-AppStream

The trigger is that DNF stopped downloading filelists (extra list of files provided by RPM packages) for a dependency resolution. That's a Fedora 40 feature <https://fedoraproject.org/wiki/Changes/DNFConditionalFilelists> inherited to RHEL 10. Packaging guidelines now forbids dependencies on files out of /usr/bin, /usr/sbin, and /etc <https://docs.fedoraproject.org/en-US/packaging-guidelines/#_file_and_directory_dependencies>. In other words, insights-client-3.2.2-2.el10.noarch does not conform to the guidelines.

Either remove that dependency, or add explicit "Provides: /usr/libexec/platform-python" to the package that is supposed to install that file.
