There could be several reasons why certain packages are absent from public repositories at http://repo.cloudlinux.com/cloudlinux/. Here are some possible explanations:

1. Repository Configuration:

   • Ensure that your server is correctly configured to use the CloudLinux repositories. Double-check the repository configuration files located  /etc/yum.repos.d/ to make sure they are pointing to the correct repositories.

2. Repository Mirroring:

   • CloudLinux may use a mirrored or distributed repository system. In such cases, not all packages might be available in every mirror. It's possible that some packages are only available in specific mirrors.

3. Package Availability:

   • Some packages might not be available in the public repository due to licensing restrictions or other reasons. They may only be accessible to specific subscription levels.

4. Package Version:

   • The package you are looking for may not have a version compatible with your current CloudLinux version. Make sure you are using a compatible version of CloudLinux.

5. Custom Packages:

   • Some packages may be custom-built or specific to CloudLinux, and may not be available in standard public repositories.

6. Subscription Level:

   • The availability of certain packages may be tied to your subscription level with CloudLinux. Some packages might only be available to higher-tier subscriptions.

7. Temporary Unavailability:

   • Occasionally, packages might be temporarily unavailable due to maintenance, updates, or other reasons. They may be restored in the future.

8. Security and Stability:

   • CloudLinux might have specific criteria for which packages are included in their public repositories. This is to ensure that packages meet their security and stability standards.

9. Specialized Repositories:

   • Some packages may be part of specialized repositories that are not included in the default repository list. You might need to enable additional repositories.

10. Contact CloudLinux Support:

    • If you are unable to find a specific package in the public repositories and it's critical for your use case, consider reaching out to CloudLinux support for clarification or assistance.

Remember that the availability of packages in a repository can be subject to change, and it's always a good idea to refer to official documentation or support channels for the most up-to-date information
