}

this is a function in g1pwsh I am trying to test.

function Configure-PSRepository {

  # Install a specific version of PowerShellGet from the virtual repository
  Install-Module -Name PowerShellGet -Force -RequiredVersion 2.2.5 -Scope AllUsers -Repository psgallery-virtual

  # Unregister unwanted package sources
  $packageSources = Get-PackageSource -ErrorAction SilentlyContinue
  $sourcesToRemove = ("chocolatey", "nuget.org", "PSGallery")
  $packageSources | Where-Object { $_.Name -in $sourcesToRemove } | ForEach-Object {
  Unregister-PackageSource -Name $_.Name -ProviderName $_.ProviderName -ErrorAction SilentlyContinue
  }

  # Register a custom chocolatey package source
  Register-PackageSource -Name "chocolatey" -Location "https://chocolatey.example.com/chocolatey/" -ProviderName "Nuget" -ErrorAction SilentlyContinue -Force -ForceBootstrap
}
