Before updating the PowerShellGet or PackageManagement, let us first check the versions of the modules we have available. If you use Update-Module, it will automatically load PowerShellGet and PackageManagement and list them as loaded PowerShell modules.
– Note: You can also use the Get-Module -ListAvailable.

As you can see above, we have version 1.0.0.1 PowerShellGet and version 1.0.0.1 Package management running.
In order to update PowerShellGet or PackageManagement, you should always install the latest NuGet provider. To do that, run the following in an elevated PowerShell prompt.
Install-PackageProvider Nuget –force –verbose

Note: If you have PowerShell 5.0 or above running. you can install both PowerShellGet and PackageManagement together. To do this on Windows 10, Windows Server 2016, or any system with WMF 5.0 or 5.1 installed, run the following commands from an elevated PowerShell prompt:
Install-Module –Name PowerShellGet –Force –Verbose
Next, If you run PowerShell 5.0 or newer, you can install the latest PowerShellGet using the following command. PowerShell 5.0 is included in Windows 10, Windows Server 2016, Windows Server 2019, any system with WMF 5.0, and 5.1 or a system running PowerShell 6.

To get the latest version, the the following command below for this.
Update-Module
Get-Module
After that you will see the latest versions of PowerShellGet and Package Management available.

To permit new modules to run, you will have to set the execution policy to RemoteSigned to allow this. For more on information on execution policy, see
