”ansible-lint error no such option –offline“ | Solution
When working with Ansible, you are likely to run into the following error:
ansible-lint: error: no such option –offline
This error occurs when using the `–offline` option with a version of `ansible-lint` that does not support it. According to our experts, this happens due to an outdated version of `ansible-lint` that lacks the `–offline` feature.
An Overview:
Impacts of This Error
- Without `–offline`, Ansible playbooks cannot be validated in air-gapped environments.
- Also, the error prevents resolving Ansible Galaxy dependencies, leading to incomplete checks.
- `ansible-lint` may not function properly, failing to enforce best practices across playbooks, roles, and collections.
Causes and Fixes
1. Outdated Version of `ansible-lint`
The `–offline` option was introduced in later versions of `ansible-lint`. Using an older version results in this error.
Click here for the Solution.
Update `ansible-lint` to the latest version.
If we have internet access, use pip to upgrade ansible-lint:
pip install --upgrade ansible-lint
However, if we are in an offline environment, the best option would be an Air-Gapped Environment:
- Download the updated package and dependencies in an internet-enabled environment.
- Transfer the package to the offline environment.
- Then, install it using:
pip install ansible-lint-<version>.tar.gz - Optionally, install `ansible-dev-tools` for better dependency management:
pip3 install ansible-dev-tools
2. Incorrect Command Usage
A typo or incorrect placement of the `–offline` option.

Verify and correct the command syntax.
- Double-check the command for errors.
- Then, ensure the option is placed correctly:
ansible-lint --offline .yml
3. Configuration Issues
Misconfigured paths in `ansible.cfg` or `.ansible-lint` files can prevent `ansible-lint` from locating required roles and collections, especially in offline mode.
Click here for the Solution.
Review and correct paths in configuration files.
- First, check `ansible.cfg` for `roles_path` and `collections_paths` settings.
- If `.ansible-lint` exists, verify settings to ensure offline mode is correctly enabled.
- Then, confirm that paths correctly point to local directories storing roles and collections.
4. Missing Dependencies
The playbook relies on roles or collections that are not available locally. The `–offline` flag prevents automatic downloads.
Click here for the Solution.
Pre-download and install all required roles and collections.
- Use `ansible-galaxy` to download required dependencies:
ansible-galaxy role download -r requirements.yml --roles-path <local_roles_directory>
ansible-galaxy collection download -r requirements.yml --collections-path <local_collections_directory> - Then. ensure the paths in `ansible-galaxy` commands match those specified in `ansible.cfg`.
5. Environment Variables Not Set
Some setups depend on environment variables to locate roles and collections. If missing, `ansible-lint` may fail.
Click here for the Solution.
Define the necessary environment variables.
- Set `ANSIBLE_ROLES_PATH` and `ANSIBLE_COLLECTIONS_PATHS`:
export ANSIBLE_ROLES_PATH=
export ANSIBLE_COLLECTIONS_PATHS=
- Then, ensure these variables point to the correct locations for roles and collections.
Prevention Strategies
Here are some tips to avoid this error in the future:
- Stay up-to-date to leverage new features and avoid compatibility issues.
- Furthermore, maintain consistent installations of `ansible-lint` across systems.
- Integrate `ansible-lint` into CI/CD pipelines to enforce best practices.
- Additionally, use `requirements.yml` files to define and install required roles and collections.
- Utilize virtual environments (`venv`) to prevent conflicts between different versions of tools.
- Regularly validate Ansible playbooks in offline environments to ensure smooth operation.
- Configure dummy fallback values to avoid undefined variable issues during linting.
