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:

  [No matching package to install: 'python3dist(pydantic) >= 2.9.2']: [Package `python3dist(pydantic) >= 2.9.2` is not present in know repositories.]
=============
[No matching package to install: 'python3dist(python-dotenv) >= 1.0.1']: [Package `python3dist(python-dotenv) >= 1.0.1` is not available in known repositories.]

[Not all dependencies satisfied]: [Package manager indicates that some dependencies couldn't be retrieved.]
=============
[This system is not registered with an entitlement server. You can use subscription-manager to register.]: [Warning that system is not registered with Red Hat subscription. This is normal occurrence on temporary VMs which do not require full subscription for their purpose.]

Issue: Two requested packages couldn't be found. Without all the dependencies, the package couldn't be build.
Resolution: Verify that both packages are present in installed repositories. Check spelling of package names and version constraints. Verify network connection between repository server and system you are building on.
