Error “Docker.ApiServices.WSL2.WslKernelUpdateNotInstalledException”

This is a trouble shooting log.

Problem

I downloaded the installer of Docker-Desktop from download page here. And executed the installer and start Docker. Then the error was displayed after starting Docker-Desktop.

Cause

Let’s see the window behind the exception window by Microsoft .NET Framework.

The WSL 2 Linux kernel is now installed using a separate MSI update package.
Please click the link and follow the instructions to install the kernel update:
http://aka.ms/wsl2kernel.

Press Restart after installing the Linux kernel.

That’s the cause of the error. We should install “WSL 2” by ourselves now.

Solution

Install WSL 2 Linux kernel whose installer is in http://aka.ms/wsl2kernel.

After installing WSL 2, restart the Docker-Desktop.
