Setup Proxy
First you’ll need to tell your PowerShell session to use your proxy. You might also need to change the TLS protocol that’s accepted. Basically, what’s happening above is just a bad error message. It’s not verbose enough to say “HTTPS failure” or anything like that.
$proxy = '<YOUR CORPORATE PROXY HERE>' # update this
[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
[system.net.webrequest]::defaultwebproxy = new-object system.net.webproxy($proxy)
[system.net.webrequest]::defaultwebproxy.credentials = [System.Net.CredentialCache]::DefaultNetworkCredentials
[system.net.webrequest]::defaultwebproxy.BypassProxyOnLocal = $true
Update Package Providers
This is similar-ish to sudo apt-get update. The first line gives you the package provider itself, the second registers PSGallery and the third installs PowerShellGet, which is basically an installer that a lot of packages use.
Install-PackageProvider -Name nuget -Scope AllUsers -Confirm:$false -Force -MinimumVersion 2.8.5.201
Register-PSRepository -Default -verbose
Install-Module -Name PowerShellGet -Scope AllUsers -Confirm:$false -Force -AllowClobber -MinimumVersion 2.2.4 -SkipPublisherCheck
