Ansible Galaxy Collection Module Not Found: Troubleshooting Guide
Encountering "Ansible Galaxy Collection Module Not Found" errors can be frustrating when working with Ansible. This guide provides a systematic approach to troubleshooting these issues, helping you identify the root cause and get your Ansible playbooks running smoothly. We will explore common causes, solutions, and best practices for managing Ansible collections.
Verifying Ansible Collection Installation
The most common reason for this error is a missing or incorrectly installed Ansible collection. Before diving into more complex solutions, ensure the collection is properly installed using the ansible-galaxy collection list command. If the collection isn't listed, you'll need to install it using ansible-galaxy collection install
Inspecting Ansible Configuration Files
Ansible relies on configuration files to determine where collections are located. Incorrectly configured paths or missing entries in the ansible.cfg file can lead to the "module not found" error. Examine your ansible.cfg file for any misconfigurations related to collection paths. The collections_paths setting defines the directories Ansible searches for collections. If this path is incorrect or missing the relevant collection, you will encounter the error. Consider using a dedicated directory for your collections to maintain organization and avoid potential conflicts. Ensure the permissions are appropriately set to allow Ansible access to these directories. Check the official Ansible documentation for detailed information on configuration settings.
Troubleshooting collections_paths
The collections_paths setting in ansible.cfg is crucial. Incorrectly configured paths prevent Ansible from locating your installed collections. To verify its configuration, check your ansible.cfg file. This file is usually located in your home directory or in the project's root. It might look like this:
[defaults] collections_paths = /path/to/my/collections Make sure /path/to/my/collections is replaced with the actual path to the directory where your Ansible collections are installed. You might need to use the absolute path. Incorrect paths will prevent Ansible from accessing modules, leading to the error.
Checking Ansible Version and Collection Compatibility
Ansible collections often have version requirements. An incompatible Ansible version can prevent a collection from functioning correctly. You may see this error if you are attempting to use a collection that is not compatible with your version of Ansible. Check the collection's documentation or the Ansible Galaxy page for information regarding compatible Ansible versions. If an update to Ansible or the collection is needed, it's often preferable to update Ansible first, as updating a collection might introduce dependencies that require a newer Ansible version. Remember to always consult the official documentation before performing any updates to avoid unforeseen complications.
| Ansible Version | Collection Compatibility | Action |
|---|---|---|
| 2.10 | Compatible with Collection X | No action needed |
| 2.9 | Incompatible with Collection X | Update Ansible or find a compatible collection |
Sometimes, seemingly unrelated issues can cause this error. For example, a problem with a virtual environment or incorrect Python path settings can lead to unexpected behavior. Make sure your Python environment is correctly set up and that your Ansible installation is consistent with your virtual environment. Consider creating a new virtual environment for your Ansible project and re-installing Ansible and relevant collections.

Utilizing Ansible-Galaxy for Collection Management
Ansible Galaxy is the official repository for Ansible collections. Using ansible-galaxy commands for installation, updating, and managing collections is recommended over manual methods. Using ansible-galaxy collection install ensures proper installation and avoids potential issues arising from manual copying or incorrect paths. Regularly updating your collections via ansible-galaxy collection update helps keep your Ansible environment up-to-date with the latest bug fixes and features, which might resolve compatibility issues. This structured approach minimizes the risk of encountering errors due to misconfigured collection paths or outdated versions.
- Use

ansible-galaxy collection listto verify installation - Use
ansible-galaxy collection updatefor updates
Remember to always consult the official Ansible documentation on collections for the most accurate and up-to-date information.
Troubleshooting Virtual Environments
If you're using virtual environments (like virtualenv or venv), ensure your Ansible installation is within the activated environment. Activating the virtual environment ensures Ansible uses the correct Python interpreter and libraries installed within that environment, preventing conflicts with system-level installations. If Ansible is not installed within the activated environment, it might use the wrong Python interpreter or library paths, resulting in the "module not found" error. Check that your environment is properly activated before running Ansible commands.
"Proper virtual environment management is crucial for avoiding conflicts and ensuring a consistent Ansible environment."
By carefully following these steps and utilizing the recommended tools, you can effectively troubleshoot and resolve "Ansible Galaxy Collection Module Not Found" errors, ensuring your Ansible automation runs smoothly.
