Unable to install module from repository

Question

Hello,

I have an issue with installing new module on windows 2016.

What I already found and applied:

[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12  
  
[system.net.webrequest]::defaultwebproxy = new-object system.net.webproxy('http://proxyXXXXXXX.com:8080')  
[system.net.webrequest]::defaultwebproxy.credentials =  [System.Net.CredentialCache]::DefaultNetworkCredentials  
[system.net.webrequest]::defaultwebproxy.BypassProxyOnLocal = $true  

Set-ItemProperty -Path 'HKLM:\SOFTWARE\Wow6432Node\Microsoft\.NetFramework\v4.0.30319' -Name 'SchUseStrongCrypto' -Value '1' -Type DWord  
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  

Nothing helps I still don't see the repository set:

Answer 1

After several attempts to resolve the issue using various commands all to no avail, I exited the powershell session and closed the terminal. I then

1. restarted the terminal,
2. started powershell,
3. ran [Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
4. then attempted the installation again ( Install-Module -Name Az -Scope CurrentUser -Repository PSGallery -Force )and it came up successful.

Many thanks for all the suggestions.

Hi，

Does this work for you？

$parameters = @{  
  Name = "PSGallery"  
  SourceLocation = "https://www.powershellgallery.com/api/v2"  
  PublishLocation = "https://www.powershellgallery.com/api/v2/package/"  
  ScriptSourceLocation = "https://www.powershellgallery.com/api/v2/items/psscript"  
  ScriptPublishLocation = "https://www.powershellgallery.com/api/v2/package/"  
  InstallationPolicy = 'Untrusted'  
}  
Register-PSRepository @parameters  

Best Regards,
Ian Xue

I'm able to issue a get-psrepository command without error but still not able to install the requested module.

I've changed the $debugpreference to "Continue" and get a detailed log. I'm not sure but I think the relevant information is :

Answer 5

Especially in these 2 lines:
DEBUG: 00:00:00.0852100 There are '0' registered sources in 'NuGet' provider.
DEBUG: 00:00:00.0857066 Source 'https://www.powershellgallery.com/api/v2' is not one of the registered sources in 'NuGet' provider.

however so far I didn't find a solution for that.
