Install Ubuntu(WSL2) on Windows 10: Because Ubuntu(WSL1) does not have debugging capabilities, install Ubuntu(WSL2) as much as possible.
The specific process is as follows:
1. What is WSL?
Windows Subsystem for Linux (WSL for short), the Linux subsystem under Windows, is a compatibility layer that can run native Linux binary executable files (ELF format) on Windows 10. It was developed by Microsoft in cooperation with Canonical. Its goal is to enable pure Ubuntu, Debian and other images to be downloaded and decompressed to the user's local computer, and the tools and utilities in the image can run natively on this subsystem.
