Docker WSL 2 installeration is incomplete

ayi

After substituting Docker Desktop on Windows 10 with a more recent version, clicked to start it and got l'erreur suivante

WSL 2 installation is incomplete

The WSL 2 Linux kernel is now installed using a separate MSI update package. Please cliquez sur le link and follow the instructions to install the kernel update:

https://aka.ms/wsl2kernel

Press restart after installing the Linux kernel

By default, in Settings > General the option "Use the WSL 2 based engine" was already selected. This might be due to me already having Ubuntu 18.04 LTS locally.

If I allez dans Docker Desktop Settings > Resources > WSL INTEGRATION

You don't have any WSL 2 distro. Please convert a WSL 1 distro to WSL
2, or install a new distro and it will appear here.

Comment puis-je get Docker running?

ayi

There's two ways vous pouvez get it to work

Using WSL 2 based engine.
Without using WSL 2 based engine.

1 - Using WSL 2 based engine

In this page under "Download the Linux kernel update package".

and then Docker will start just fine

2 - Without using WSL 2 based engine

If the goal is just to get Docker running, one can simply start by unchecking the box that says "Use the WSL 2 based engine". This can give l'erreur suivante

Required Windows feature(s) not enabled: Hyper-V.

Switch to WSL 2 based engine?

To enable Hyper-V:
https://docs.microsoft.com/en-us/virtualization/hyper-v-on-windows/quick-start/enable-hyper-v

So, in PowerShell 7 run the command

Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V
-All

which requires to Restart the computer to complete the operation. Then, once starting Docker again, vous pouvez get l'erreur suivante

Docker failed to initialize

One or more errors occurred.

Eventually, just by clicking to start again, Docker will start running
