The following instructions are for Ubuntu 18.04, but if you happen to use a different WSL distribution, you can follow Docker's installation guide for your distro from Docker's installation docs.

Windows Package Manager Preview

If you're already familiar with what a package manager is, feel free to skip this paragraph. If you're still reading, you're going to love this! A package manager is designed to help you save time and frustration. Essentially, it is a set of software tools that help you automate the process of getting software on your machine. You specify which apps you want installed, and it does the work of finding the latest version (or the exact one you specified) and installing it on your machine.

Just about every developer has wanted a native package manager in Windows. That day is finally here. You are going to be able to winget install your way to bliss. One of the best parts is that it is open source. I had to pinch myself when I was able to winget install terminal, and then winget install powershell, and then winget install powertoys. You get the idea, and If you do not see an app you use, just create a new manifest, and submit a pull request.
