WSL isn’t new to this audience, and with the new improvements over WSL2 Microsoft has enabled access to Linux from Windows to even greater audiences. While you can download multiple distributions of Linux from the Microsoft Store on Windows 10. If you are an existing WSL user, chances are you don’t want to download a separate new version of the existing Linux that you already have installed.
In this guide we will show you how to upgrade your existing Ubuntu 18.04 TLS to 20.04 TLS without installing a separate instance of Ubuntu so you can keep all your existing OS and all it’s configuration the way is.
You can install the latest Ubuntu 20.04 from the Microsoft Store, however, if you already have a previous version installed this will become a separate instance, unless you want to have two Ubuntu 18.04 and 20.04 side by side. There is no need to download a separate distribution. The best way to upgrade to the latest is by upgrading the existing Ubuntu version.
Assuming you have 18.04 LTS Ubuntu installed with WSL or WSL2.
