"Unable to resolve package source" when registering PowerShell repository

curtis.denotter_1361

Using a ProGet installation with built-in user security enabled, I am trying to register my PowerShell feed as a repository and install a module from it. I am using a Personal API token to handle authentication. I am trying to run the following in PowerShell:

$progeturl = "my-proget-url.example.com"
$repository = "third-party-powershell"
$apikey = Read-Host -MaskInput # Prompts for API Token

$password = ConvertTo-SecureString $apikey -AsPlainText -Force
$credential = New-Object System.Management.Automation.PSCredential("api", $password)
Register-PSRepository -Name $repository -SourceLocation "https://${progeturl}/nuget/${repository}/" -Credential $credential

This results in the following response:

WARNING: Unable to resolve package source 'https://my-proget-url.example.com/nuget/third-party-powershell/'

The Get-PSRepository command shows my new "third-party-powershell" module in the list, but when I try to install a module, I get the following output:

PS C:\> Install-Module -Name "PsIni" -RequiredVersion "3.1.2" -Repository "third-party-powershell"
WARNING: Unable to resolve package source 'https://my-proget-url.example.com/nuget/third-party-powershell/'.
Install-Package: No match was found for the specified search criteria and module name 'PsIni'. Try Get-PSRepository to see all available registered module repositories.

If I attempt to register the repository without passing the credential, I get the error: Register-PSRepository: The specified Uri 'https://my-proget-url.example.com/nuget/third-party-powershell/' for parameter 'SourceLocation' is an invalid Web Uri. Please ensure that it meets the Web Uri requirements.

Using the -Credential flag in the Install-Module call does not make a difference in the returned output. I have no configured proxy that could be impacting the register or install calls.

I'm a little stumped! How can I use PowerShell feeds configured in my ProGet installation?

Hi @curtis-denotter_1361 ,

It looks like you're following the right steps; here is our HOW-TO guide on the topic:
https://docs.inedo.com/docs/proget-powershell-private-module-repository

If I had to guess, the issue is with HTTPS/TLS resolution. That's what most search results for "Unable to resolve package source" came up with, anyway. You'd have to use a tool like Wireshark to be sure, since the error message from PowerShell isn't very helpful.

You can force PowerShell to use TLS12:
[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12

It might also be certificate related. You may get a better error message if you do like a Invoke-WebRequest to your ProGet URL.

Cheers,

Hello and thanks for the suggestions, @atripp!

I tried doing an Invoke-WebRequest against the repository URL. It appears to work fine, which is nice but also a pain as it indicates the problem is more complicated.

PS C:\> [Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
PS C:\> $test = Invoke-WebRequest -UseBasicParsing "https://${progeturl}/nuget/${repository}/"
Invoke-WebRequest: You must log in to issue this request because the anonymous user does not have the Feeds_ViewFeed privilege.
PS C:\>
PS C:\> $test = Invoke-WebRequest -UseBasicParsing "https://${progeturl}/nuget/${repository}/" -Credential $credential
PS C:\> $test

I will attempt to use a tool like Wireshark or Fiddler to see what's going on.
