Install-Module reports all modules from PSGallery as unsigned.

[AspenForester]

Prerequisites

• Write a descriptive title.
• Make sure you are able to repro it on the latest released version
• Search the existing issues.

Steps to reproduce

When running install-module (as imported from PowerShellGet 3.023), Install-PSResource returns an error stating that the target module is unsigned.
Install-PSResource: The signature status for 'Microsoft.Graph' file 'Microsoft.Graph.psd1' is 'NotSigned'.

Expected behavior

`Install-Module` which is supposed to be a compatibility mode wrapper for `Install-PSResource` should successfully install modules.

Actual behavior

> Install-Module Microsoft.Graph -RequiredVersion 2.30.0 -Repository PSGallery

Untrusted repository
You are installing the modules from an untrusted repository. If you trust this repository, change its Trusted value by
running the Set-PSResourceRepository cmdlet. Are you sure you want to install the PSResource from 'PSGallery'?

Visuals

Using Install-PSResource directly works normally, even in the same session.

Edit: Seems like there is an issue for this already: PowerShell/PowerShellGet#48.

From the error message it seems like you are using PowerShellGet v3.0.23-beta23 (there is no stable version of this release AFAIK):

• https://www.powershellgallery.com/packages/PowerShellGet/3.0.23-beta23

This is a shim or proxy for PSResourceGet. More reading:

• https://learn.microsoft.com/en-us/powershell/module/powershellget
• https://github.com/PowerShell/PowerShellGet

The last link is where you should create an issue for this.

Having said that, it looks like that project isn't highly prioritized. There have never been a stable v3 release of it. Don't expect a swift solution.
