If you’ve accidentally deleted the PowerShell Gallery (PSGallery) repository from your system, you can restore it using the following command.
Register-PSRepository -Default
In fact, if you try to re-register the PowerShell Gallery using the same method that you’d register a custom repository (see below) …
$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
… you get the following exception in return:
Register-PSRepository : Use 'Register-PSRepository -Default' to register the PSGallery repository.
