Get Powershell NuGet to install modules if it complains it’s offline: set a better TLS cipher version

let-powershell-install-package-managers-and-nuget-modules-when-it-complains-about-unable-to-download-from-uri.ps1

<# Assuming your computing device is online and can get through the firewall,
   it is possible (because that was the problem in my case), that Powershell
   chose an internet security cipher that is outdated or not available. 
   
   Errors typically include: 
     WARNING: Unable to download from URI 'https://go.microsoft.com/fwlink/?LinkID=627338&clcid=0x409' to ''.
     WARNING: Unable to download the list of available providers. Check your internet connection.
       Install-PackageProvider : No match was found for the specified search criteria for the provider 'NuGet'. 
       The package provider requires 'PackageManagement' and 'Provider' tags. Please check if the specified 
       package has the tags.

   provides a solution that worked in my case. #>
  
   
<# 1: Tell .Net to use an available TLS protocol #>
[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12

<# 2: Retry the failed command, like: #>
Find-PackageProvider
 
<# or #>
Install-PackageProvider -Name NuGet
