Import-PSGetRepository fails silently to import UNC based PowerShellGet v2 repositories on PowerShell 5.1
(It works on PowerShell 7.3.8)

Steps to reproduce:

1. Register an UNC PowerShellGet v2 repository (remote PC requried) on PowerShell 5.1:

Register-PSRepository -Name Test -SourceLocation \\Server\RepoPath -InstallationPolicy Trusted

2. Try to import the PowerShellGet v2 repository:

Import-PSGetRepository -Verbose -Force

3. The UNC repository is not imported:

Get-PSResourceRepository

thanks for reporting @kborowinski this needs investigation

[alerickson]

I wasn't able to repro this. @kborowinski if you open the xml file here: %LocalAppData%\PSResourceGet\PSResourceRepository.xml do you only see the PSGallery registered? If so can you delete this file then try running Import-PSGetRepository -Verbose -Force again?

[kborowinski]

@alerickson:

1. I see only the PSGallery registered:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <Repository Name="PSGallery" Url="https://www.powershellgallery.com/api/v2" APIVersion="v2" Priority="50" Trusted="false" />
</configuration>

2. Deleting the file and executing Import-PSGetRepository -Verbose -Force does not help.

I must stress that this bug happens only on PowerShell 5.1, not on PowerShell 7.3.8 or higher. I've tried this on six different computers now, with the same results (two domain members and two standalone at work, and two at home)

Visuals:

As you can see in the verbose output of command Import-PSGetRepository -Verbose -Force on PowerShell 5.1, it looks like the cmdlet finds two repos but nothing gets registered -> Verbose: Selected NuGet repositories.:

On PowerShell 7.3.8 it looks like this:

And for completeness, visuals on the PowerShell 7.3.8:

If you want me to do any more tests, will be glad to help!

@SydneyhSmith @alerickson OK, I've found the issue with Import-PSResourceGet on PowerShell 5.1. and will push a PR later today.

Edit:
I've missed your PR request, sorry. If I can suggest a slight change to the proposed PR as there is still a problem with verbose message on PowerShell 5.1
