oneget: error trying to install package provider (for powershell core)

I’ve been checking in on this issue for a while and finally have a workaround that worked on my machine. Just run this in Core:

Get-ChildItem -Path $env:PSModulePath.Split(';') -Filter 'PackageManagement' -Directory -ErrorAction SilentlyContinue |
    Get-ChildItem -Directory |
    Where-Object -Property Name -Match '\d*\.\d*\.\d*' |
    Get-ChildItem -Filter 'netstandard2.0' -Directory |
    ForEach-Object -Process {
        foreach ($clr in 'fullclr', 'coreclr') {
            Copy-Item -Path $_.FullName -Destination "$($_.Parent)\$clr" -Recurse -ErrorAction SilentlyContinue
        }
    }

This lead me in the direction of fixing this problem for me in 7.2.5. $env:PSModulePath had “C:\Program Files\WindowsPowerShell\Modules” before “C:\Program Files\PowerShell\7\Modules”. When I made the v7 path the first item I was able to install modules again.

Strangely, attempting to Update-Module PackageManagement reports an issue, but otherwise I experience no issues.

PS > Update-Module PackageManagement
Update-Module: Module 'PackageManagement' was not installed by using Install-Module, so it cannot be updated.

PS Version: 7.2.2 Same problem.

This was a bug fixed in PowerShell 7.1. See https://github.com/PowerShell/PowerShell/pull/12203

I may be able to prepare for you small .NET Core (.NET 7) WinForms powered app with powershell (core) inside with 3 rows of Powershell. It is small part of bigger applications installing IIS, url rewrite etc on WinServer 2016/2019 so we need to get nuget provider there

Same problem in 7.2.3 too. I see it in both Windows powershell and powershell core.

I am trying to update DBATOOLS module and get this…

Import-PackageProvider: No match was found for the specified search criteria and provider name 'NuGet'. Try 'Get-PackageProvider -ListAvailable' to see if the provider
exists on the system.

NuGet provider is required to continue
PowerShellGet requires NuGet provider version '2.8.5.201' or newer to interact with NuGet-based repositories. The NuGet provider must be available
 in 'C:\Program Files\PackageManagement\ProviderAssemblies' or 'C:\Users\chamilton\AppData\Local\PackageManagement\ProviderAssemblies'. You can   
also install the NuGet provider by running 'Install-PackageProvider -Name NuGet -MinimumVersion 2.8.5.201 -Force'. Do you want PowerShellGet to    
install and import the NuGet provider now?

Update-Module: NuGet provider is required to interact with NuGet-based repositories. Please ensure that '2.8.5.201' or newer version of NuGet provider is installed.

If I run Get-PackageProvider -ListAvailable though, I see that nuget is already installed…
