Unable to Install NuGet Provider

While writing my last post, I uncovered a problem on one of my lab machines:

So much words and errors.

Background

The error happens due to the deprecated nature of SSL 3.0 and TLS 1.0.
You can confirm your configuration by opening a PowerShell prompt and running the following command:
[Net.ServicePointManager]::SecurityProtocol
If you get Ssl3, Tls returned, then your system is configured to use the deprecated protocols. (In my case, my system was a freshly installed Windows Server 2016).

Resolution

You need to update the .NET cryptography settings.  To do so, run the following commands from an elevated PowerShell console:
Set-ItemProperty -Path 'HKLM:\SOFTWARE\Wow6432Node\Microsoft\.NetFramework\v4.0.30319' -Name 'SchUseStrongCrypto' -Value '1' -Type DWORD

Set-ItemProperty -Path 'HKLM:\SOFTWARE\Microsoft\.NetFramework\v4.0.30319' -Name 'SchUseStrongCrypto' -Value '1' -Type DWORD
Close and restart PowerShell, and then re-run:
[Net.ServicePointManager]::SecurityProtocol
The result should show Tls, Tls1, Tls12.  You can then try to install or update NuGet and PowerShellGet.
