Why are we getting this error and what is the solution for unable to install and download NuGet provider?

Find PowerShell version

Find the PowerShell version that is running on the system. We are going to use the Get-Host cmdlet in Windows Server 2016.

Check Transport Layer Security protocols

PowerShell 5.1 enables SSL 3.0 and TLS 1.0 for secure HTTP connections by default. Let’s confirm that with the next step.

Check the supported security protocols on the system.

[PS] C:\>[Net.ServicePointManager]::SecurityProtocol
Ssl3, Tls

As we can see, the security protocols defined in the system are SSL 3.0 and TLS 1.0. Both of the security protocols are deprecated.

Follow below steps to resolve the above error

First, check the SSL version with below command


Solution for unable to install NuGet provider for PowerShell


Now that we gathered all the information, we are going to enable TLS 1.2 on the system. Run both cmdlets to set .NET Framework strong cryptography registry keys. After that, restart PowerShell and check if the security protocol TLS 1.2 is added

The first cmdlet is to set strong cryptography on 64 bit .Net Framework (version 4 and above).

Set-ItemProperty -Path ‘HKLM:\SOFTWARE\Wow6432Node\Microsoft.NetFramework\v4.0.30319’ -Name ‘SchUseStrongCrypto’ -Value ‘1’ -Type Dword

The second cmdlet is to set strong cryptography on 32 bit .Net Framework (version 4 and above).

Set-ItemProperty -Path ‘HKLM:\SOFTWARE\Microsoft.NetFramework\v4.0.30319’ -Name ‘SchUseStrongCrypto’ -Value ‘1’ -Type Dword

Restart Powershell and check for supported security protocols.


Run again Install-Module Az.Accounts

Post installation, Import Modules ( Installed Modules can be seen in C:\Program Files\WindowsPowerShell\Modules)

Similarly do for Azure storage modules

Conclusion:

In this article, we learned why we are unable to install Azure &NuGet provider for PowerShell. The solution to this problem is configuring TLS1.2 or higher on the system. After that, you can install NuGet & Azure Modules for PowerShell
