VMware PowerCli installation fails

VMware powerCli installation fails with the below:

PS C:\Users\Administrator> Install-Module -Name VMware.PowerCLI                                                                                                                                                                                 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\Administrator\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?

Untrusted repository
You are installing the modules from an untrusted repository. If you trust this repository, change its
InstallationPolicy value by running the Set-PSRepository cmdlet. Are you sure you want to install the modules from
'PSGallery'?

Workaround: install PowerShell by skipping publisher checks:

install-module vmware.powercli -scope AllUsers -force -SkipPublisherCheck -AllowClobber

Cause: This is due to the fact that the certificate we used to sign the modules was replaced with a new one from a new publisher.
