Here is a snippet of how to disable certificate checks on PowerShell 7 and above on Windows and Linux / Debian 11.

if ($PSVersionTable.PSEdition -eq 'Core') {
	$Script:PSDefaultParameterValues = @{
        "invoke-restmethod:SkipCertificateCheck" = $true
        "invoke-webrequest:SkipCertificateCheck" = $true
	}
} else {
	Add-Type @"
		using System.Net;
		using System.Security.Cryptography.X509Certificates;
		public class TrustAllCertsPolicy : ICertificatePolicy {
			public bool CheckValidationResult(
				ServicePoint srvPoint, X509Certificate certificate,
				WebRequest request, int certificateProblem) {
				return true;
			}
		}
"@

	[System.Net.ServicePointManager]::CertificatePolicy = New-Object TrustAllCertsPolicy
}

On my Debian 11 VM, the ‘exit’ command in a PowerShell script does not work as expected.

The script stops working, but the process does not exit either.

Now I use this to exit immediately.

[System.Environment]::Exit(0)

I just found out that on my Debian 11 VM in PowerShell the key combination Ctrl+C does not work.

The script is not terminated by this, unlike expected.

I added the following code and now it works.

add-type -typedefinition @"
using System;
using System.IO;

public class CtrlCHandler
{
	public static void Main()
	{
		System.Console.CancelKeyPress += (s,e) => System.Diagnostics.Process.GetCurrentProcess().Kill();
	}
}
	
"@

[CtrlCHandler]::Main()
