Start by reproducing the reported Install-Module Az command in PowerShell and inspect the registered PowerShellGet repositories, especially PSGallery and PSGallery1. Compare the repository's setup guidance with the observed error; done means the installation path is verified or the required repository configuration is clearly documented.
