Instead of running Linux on a separate PC or a Virtual Machine, Windows Subsystem for Linux (WSL) runs up to nine different versions at the same time. Windows Subsystem for Linux (WSL) is a compatibility layer for running Linux binary executables on a Windows operating system. It allows users to run Linux commands and programs directly on their Windows machine without the need for a virtual machine or dual-booting.
There is a major problem using Windows 10/11 Windows Subsystem for Linux WSL. It shows up when trying to adjust an SSH private key permissions to Read Only using chmod 400. This is a requirement when trying to connect SSH (port 22) to a remote Linux server. It is required when connecting to nearly any version of Linux.
