WARNING: Unable to find package sources.

Above is the output

[anamnavi]

thanks for following up @AdamSheltz. Can you run:
Unregister-PSRepository PSGallery
Register-PSRepository PSGallery -Default

This will unregister PSGallery from PowerShellGet, and then register it PSGallery again to PowerShellGet which will also register PSGallery as a package source. Then you should be good to go and be able to run the original commands. Let us know if this works

@AdamSheltz , thanks for following up! I mistyped the second command I suggested running, it should instead be:

Register-PSRepository -Default

You may notice a red warning text saying the following but you can ignore that :
Value cannot be null.
Parameter name: input

Note: you do not need to run the first Unregister-PSRepository PSGallery command again, just the Register-PSRepository -Default one listed above.

After running the above command, if you run:
Get-PackageSource you should see PSGallery listed there. And then be able to run the original commands you were attempting to run.

@AdamSheltz could you please screenshots of everything being run and outputted when you run the commands? This would provide more info to us and help debug better.

Could you run the commands again, but with -Verbose and -Debug tacked on the end?
So run:
Unregister-PSRepository PSGallery -Verbose -Debug
Register-PSRepository -Default -Verbose -Debug
Get-PSRepository -Verbose -Debug
Get-PackageSource -Verbose -Debug

At this point, Get-PackageSource should have PSGallery, and should like the following I've circled in red:

If that is not listed, run:
Register-PackageSource -Name PSGallery -ProviderName PowerShellGet
and then try Get-PackageSource again.

Can you try the running the following:
Install-Module "PowerShellGet" -RequiredVersion "2.2.5" -Scope CurrentUser -AllowClobber -Force

We want to try installing a fresh version of PowerShellget (and PackageManagement which gets installed as a dependency) to the current user's default module path in case the other one was corrupted.
