How to resolve dependencies of locally downloaded packages, when package A depends on B.

[john 517501]

I have simple playbook where trying to install the Debian packages downloaded locally in my server. This playbook runs on localhost and install the Debian packages in the same system. But this playbook gives an error "Dependency is not satisfiable for some of the packages even tough the dependency package is available in the local repository.

I can download all the dependencies required for the specific package in my local repository using apt-get install --download-only package_name

But in my playbook, i should have a mechanism to install the dependencies first than install the actual package. This task should be dynamic, playbook should resolve the dependencies by itself for any package install.

When the package has dependency over another package, How the playbook resolve dynamically.

Some of the options explored:

Using ordered indexed_items, using gdebi.. Looking for efficient Logic.

install_dependencies.yml

Hii

How about just installing the deb files in the correct order?

Sometimes the best solution is to use the commands.

Both tasks can be replaced by this

- command: dpkg -iR {{ remote_media_directory }}

[john 517501]

Thanks for your response.

I tried installing correct order(This would be more of like manual), what if there are many dependency packages for specific Debian package. I am looking for dynamic solution to resolve this issue.
