Using the checkout action to pull a dependency repository via ssh

- name: Checkout common-modules@${{ steps.set_versions.outputs.MODULE_VERSION }}
      uses: actions/[email protected]
      if: steps.set_versions.outputs.MODULE_APPS && steps.run_condition.outputs.RUN_CONDITION
      with:
        repository: ${{ inputs.COMMON_MODULE_REPO }}
        ssh-key: ${{ secrets.COMMON_MODULE_SSH }}
        ref: ${{ steps.set_versions.outputs.MODULE_VERSION }}
        path: common_modules

I am seeing the following error:
Error: Unable to locate executable file: ssh. Please verify either the file path exists or the file can be found within a directory specified by the PATH environment variable. Also check the file mode to verify the file is executable.

We have changed the version we are using back and forth and are still having the issue.
Is the image it's pulling missing the ssh executable or is this a misleading error?

Hello @ndlanier

Having the same issue and was able to pin point that this seems to happen only on self-hosted runners due to missing ssh-agent. Using ubuntu-latest and it works.

Check this issue: actions/runner#3490
