Voice mode install fails — 401 Unauthorized on internal Foundry Local NuGet feed #4814

Description

@mlohr

Describe the bug

Running  /voice  to enable dictation transcription fails during runtime installation with:

Voice runtime install failed: Error: Failed to download Microsoft.AI.Foundry.Local.Core 1.2.3 from any configured feed (api.nuget.org, pkgs.dev.azure.com): Download failed with status 401: https://pkgs.dev.azure.com/aiinfra/2692857e-05ef-43b4-ba9c-ccf1c22c437c/_packaging/7982ae-ed19-4a35-a362-a96ac99897b7/nuget/v3/flat2/microsoft.ai.foundry.local.core/1.2.3/microsoft.ai.foundry.local.core.1.2.3.nupkg

Environment:

• GitHub Copilot CLI version: 1.0.83
• OS: macOS (darwin-arm64)
• Reproduces consistently across attempts

Troubleshooting already tried:

• Confirmed this is unrelated to local  az login  / Azure tenant — the feed ( pkgs.dev.azure.com/aiinfra/... ) is a Microsoft-internal ADO org, not part of my organization's Azure tenant, so personal Azure credentials shouldn't be involved in this download at all.
• Verified CLI is on the latest version ( 1.0.83 ), no pending update.
• The failure is consistent, not transient (retried across multiple sessions/times).

Expected behavior: Voice runtime dependency should download successfully using the CLI's own bundled/managed authorization to the internal feed, without requiring any user-side Azure credentials.

Impact: Cannot enable  /voice  dictation transcription feature at all.

Affected version

GitHub Copilot CLI 1.0.83.
