Given following log snippets, their explanation, and nothing else, explain what failure, if any, occurred during build of this package.

  Snippets are in a format of [X] : [Y], where [X] is a log snippet, and [Y] is the explanation.

  Snippets are delimited with '================'.

  Drawing on information from all snippets, provide a concise explanation of the issue and recommend a solution.

  Explanation of the issue, and recommended solution, should take a handful of sentences.

  Snippets:

  [Error: Transaction test error:
  file /etc/dnf/dnf.conf from install of libdnf5-5.2.8.1-1.fc42.s390x conflicts with file from package dnf-data-4.22.0-1.fc40.noarch
]: [File from one of the installed packages conflicts with file already present on the build system.]

Issue: File `/etc/dnf/dnf.conf`, which is provided by libdnf5 package, is also tracked as being provided by already installed `dnf-data` package. This causes irreconcilable conflict, leading to build failure.
Resolution: Ensure that no requested package conflicts with an already installed package. This will require manual revision of package dependencies.
