Proxy Issues with Install Module

Question

Running the following setup:

• Server 2012 R2
• PSVersion: 4.0
• WSManStackVersion: 3.0
• Git version 2.11.1
• Package Management Preview - x64: 10.0.10586.117
• SharpZipLib: 0.86.0
• NuGet: 2.8.5.208

Trying to install the posh-git module gives:

PowerShellGet\Install-Module posh-git -Scope CurrentUser

But getting

PackageManagement\Install-Package : No match was found for the specified search criteria and module name 'posh-git'.

When trying Get-PackageSource and Get-PSRepository I get

WARNING: Unable to find package sources

and

WARNING: Unable to find module repositories.

I'm sitting behind a TMG proxy and tried using the -Proxy switch and setting setting winttp proxy with no luck.

Solution 1

A per Keith Hill's suggestion, adding the PowerShellGallery repo manually worked:

Register-PSRepository -Name PSGallery -SourceLocation https://www.powershellgallery.com/api/v2

I had trouble getting this working with the -proxy switch, so I set the proxy via netsh which did the trick:

netsh winhttp set proxy proxy-server="http=myproxy:8080"

Solution 2

Proxy can be set via -Proxy parameter of many network cmdlets or $PSDefaultParameterValues = @{ "*:Proxy"="http://proxy:port" }

Try adding the PowerShellGallery repo manually Register-PSRepository -Name PSGallery -SourceLocation https://www.powershellgallery.com/api/v2/ -Proxy ... -ProxyCredential (Get-Credential). If that works, make sure Get-PSRepository returns the newly registered repo.

Thanks Keith, that did the trick in the end. I've since made an exception in my proxy for the machine and noticed that PowerShell 5.1 seems to be a bit easier to configure in that respect.

If you are having issue with Register-PSRepository returning errors, first run Get-PSRepository. You might find the it is registered is untrusted, in which case you should use Set-PsRepository
