[Sandbox Test]: WinGet failed to download installer file with proper name

[Dragon1573]

Relevant area(s)

WinGet CLI

Relevant command(s)

winget install

Brief description of your issue

In a Windows Sandbox instance launched by SandboxTest.ps1, the winget.exe failed to download installer file with proper name.

Manually check $env:TEMP\WinGet\<package_identifier_and_version>\ folder, the installer file was named with its SHA256 value WITHOUT PROPER FILE EXTENSION. This caused the downloaded installer file cache unable to be found by following steps. The package can't be successfully installed.

Steps to reproduce

1. Make sure you've cloned microsoft/winget-pkgs and checked out the latest master branch.
2. Try Tools/SandboxTest.ps1 <any local manifest folder> to install a local manifest inside Sandbox instance.

Expected behavior

The package should be installed as expected. For portable executables, the downloaded package should be automatically added to $env:PATH and an ARP Entry should be written into the Windows Registry.

Actual behavior

The inferred installer file will be shown as downloaded and hash value verified.

But NO ARP ENTRIES will be shown, EVEN IF it's a portable executable (ARP Entries should be written by winget.exe itself).

Important

It seems this issue only happens when invoking winget.exe -m <local_manifest_folder>.

When using winget.exe upgrade or winget install with remote sources (mostly winget), no errors occur.

[Dragon1573]

Test with local manifests

Test with winget remote source

[Dragon1573]

All latest 5 versions of winget.exe failed to install local manifests. Can't sure if it's a severe bug of Windows Sandbox instance only.

[Dragon1573]

On Windows 11 Pro WorkStation host device, the latest pre-release version v1.29.50-preview also failed to install package properly.

👀 On another Windows 11 Pro host device, v1.29.50-preview works fine ...

It's really weird ...
