PowerShell Restore Default Gallery Repository

1 minute read

When installing PowerShell or PowerShell core on a system it comes configured with a default repository for PowerShell Gallery which can be used to install modules without any further configuration.

Yesterday I was installing the AZ Module on my Mac machine but when trying to install the module all I got was the following error

Install-Module -Name Az

PackageManagement\Install-Package : No match was found for the specified search criteria and module name 'Az'. Try Get-PSRepository to see all available registered module repositories.
At /usr/local/microsoft/powershell/6/Modules/PowerShellGet/PSModule.psm1:9349 char:21
+ ...          $null = PackageManagement\Install-Package @PSBoundParameters
+                      ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo          : ObjectNotFound: (Microsoft.PowerShel\u2026lets.InstallPackage:InstallPackage) [Install-Package], Exception
+ FullyQualifiedErrorId : NoMatchFoundForCriteria,Microsoft.PowerShell.PackageManagement.Cmdlets.InstallPackage

Issuing a Get-PSRepository was yielding the following:


WARNING: Unable to find module repositories.

Apparently I accidentally removed the repository from my system and trying to reinstate it using the standard way of registering a new repository like this

$Repository = @{
    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 @Repository

Was just yielding the following exception

Register-PSRepository : Use 'Register-PSRepository -Default' to register the PSGallery repository.

It turns out to restore the default PowerShell Gallery repository the only required command is

Register-PSRepository -Default

This will return no output but you can easily verify it worked like this


Name                      InstallationPolicy   SourceLocation
----                      ------------------   --------------
PSGallery                 Untrusted            https://www.powershellgallery.c

Hope this will help in case you accidentally remove the default PSGallery repository.
