Issues with Registering PSRepository and Installing VMWare PowerCLI Module - powershell

Question

My Setup: Windows 10.17134, PowerShell 5.1.17134.407
When trying to Register a new PSRepository using the Code below….
Register-PSRepository -Name "PSGallery" –SourceLocation "https://www.powershellgallery.com/api/v2/" -InstallationPolicy Trusted
….it gives me the following error:
FullyQualifiedErrorId : UseDefaultParameterSetOnRegisterPSRepository,Register-PSRepository
I am not able to install the VMWare PowerCLI Module with this command:
Save-module -Name vmware.powercli -path c:\temp
….it gives me this error:
FullyQualifiedErrorId : NoMatchFoundForCriteria,Microsoft.PowerShell.PackageManagement.Cmdlets.SavePackage

Answer 1

Here are the results of a days googling
I'm running
Register-PSRepository
-Name "PSGallery"
–SourceLocation "https://www.powershellgallery.com/api/v2/"
-InstallationPolicy Trusted
(multiline for clarity)
and I kept getting
Register-PSRepository : Use 'Register-PSRepository -Default' to
register the PSGallery repository. At line:1 char:1
+ Register-PSRepository -Name "PSGallery" –SourceLocation "https://www. ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidArgument: (PSGallery:String) [Register-PSRepository], ArgumentException
+ FullyQualifiedErrorId : UseDefaultParameterSetOnRegisterPSRepository,Register-PSRepository
I assumed this was to do with proxy settings so I tried all of the various methods of setting the proxy in powershell to no avail.
Finally I ran
Get-PSRepository
and discovered that the repository was already registered, it was just untrusted
So I ran
Set-PSRepository -Name PSGallery -InstallationPolicy Trusted
The original reason I had for doIng this is because when I run
Install-PackageProvider -Name NuGet -Force -Scope CurrentUser
I get
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. At line:1 char:1
+ Install-PackageProvider -Name NuGet -Force -Scope CurrentUser
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidArgument: (Microsoft.PowerShel\u2026tallPackageProvider:InstallPackageProvider)
[Install-PackageProvider], Exception
+ FullyQualifiedErrorId : NoMatchFoundForProvider,Microsoft.PowerShell.PackageManagement.Cmdlets.InstallPackageProvider
Unfortunately, making the repository trusted did no help with my issue
... and the original reason for doing this was so I could run
Install-Module -Name SqlServer -Force -Verbose -Scope CurrentUser
Which was failing (sorry no error message, it was so long ago)
After all my fiddling however, this statement now works without error.
Not sure if it was all the proxy config, or making NuGet trusted or both

Answer 2

I've been chasing this problem for days. I isolated it to Install-PackageProvider not being able to download:
Microsoft.PackageManagement.NuGetProvider-2.8.5.208.dll
In my case, my company does not allow us to download DLLs from the internet without due process. I engaged due process and got an approved copy of the DLL. Then it needs to be placed here:
$env:ProgramFiles\PackageManagement\ProviderAssemblies\nuget\2.8.5.208\Microsoft.PackageManagement.NuGetProvider.dll
Note the version becomes a folder and is stripped from the name.
Manually doing so eliminates the need to run Install-PackageProvider. Some articles state that Import-PackageProvider is necessary to get PowerShell to recognise it. But, I did not need to do the Import. Just try Install-Module -Name SqlServer -Force again.
