Please try running wsl --set-version Ubuntu-18.04 2 or with the version you are using

And I have installed the Linux kernel update package.

[blackfan23]

Uninstall Ubuntu again. And choose another flavor/distribution and try once more.

Uninstall Ubuntu again. And choose another flavor/distribution and try once more.

I uninstall Ubuntu and then reinstall it ,I have the same message.

[blackfan23]

Then I am at a loss. You could try to install the kernel update again as well (link in the error message). Have you activated virtualization? I cant read the exact message due to my language shortcomings though.

I have reinstalled the kernel update and activated virtualization ,but it do not work.

[blackfan23]

Alright, but I am at a loss, sorry. Hope this gets resolved for you soon.

My windows version is 10.0.19041.153.
I have installed "wsl_update_x64.msi",but I still have the mssage:"WSL 2 requires an update to its kernel component. "

[wornut]

I have the same problem @10.0.19041.153.
When I have check with wsl -l -v. All wsl are stop running so I run bash.exe (maybe ubuntu.exe) the powershell directly. It will work. I got the wsl back and still work file.

[aramis4791]

I am also facing the same issue. I tried to update the version before and after stopping the distro without any luck. If I try to install the wsl2 update again I get the error message that update is applicable only for machines with Windows Subsytem for Linux as shown below

[mario-lukic]

In case you have problem launching WSL2 after Kernel Update (saying it needs an update). Right click on MSI -> Uninstall. Then you can install Kernel update again and you should be able to launch WSL2 again.

I tried to unistall and install Kernel update ,it does not work .
When i run " wsl --set-default-version 2" ,I still have the message "WSL 2 需要更新其内核组件。有关信息，请访问 https://aka.ms/wsl2kernel"

[717009629]

I have solved the problem

I Install and reinstall the Kernel Update ,but there is no "kernel" file in "C:\Windows\System32\lxss\tools".
I Extract the "wsl_update_x64.msi" file, then I get The "Kernel" file ,then I copy it to "C:\Windows\System32\lxss\tools". Then I can update wsl2.

The extract command is : msiexec /a "wsl_update_x64.msi" /qb TARGETDIR="D:\xx"

[aramis4791]

Thanks. It solved the issue I was facing in upgrading to WSL 2.

I met the same problem and solved by this way.

[karol-preiskorn]

wsl --set-version Ubuntu

I think that

I am also facing the same issue. I tried to update the version before and after stopping the distro without any luck. If I try to install the wsl2 update again I get the error message that update is applicable only for machines with Windows Subsytem for Linux as shown below

Run from cmd as admin (I have the same confiuson)...

This should be added to the instructions page. PLEASE! or fix the installer to copy the kernel file over and apply changes. This saved a lot of time.

[UkrainianCitizen]

@khpatel4991 This is a hideous bug and it should be fixed ASAP not to be put on the instructions page.

[Bdoom]

Same thing, still haven't tried fix yet though

[UkrainianCitizen]

@Bdoom It seems that it worked for everyone who has tried it in this thread.

[PasqualeT-Git]

msiexec /a "wsl_update_x64.msi" /qb TARGETDIR="D:\xx"

This command doesn't work to me and I can't extract the kernel, can someone help me please?
This is the error that I get when i tried running the command:

[nadddy]

Use ZIP to extract wsl_update_x64.msi to any folder. Copy FID_LXSS_KERNEL from extracted location to C:\Windows\System32\lxss\tools\ and rename this file to "kernel"
After this wsl2 works.

[etrimbymchd]

I had this issue. Now fixed..
HOWEVER I was wanting to move all my dev work from 18.04 to 20.04 anyway. so
I uninstalled all distros.
Disabled WSL in windows features.
Rebooted
Re-enabled WSL
Re-booted
Install Distro and all is good.

I tried this but still installer did not detect WSL and I had to copy file manually.
Strange that MS is not fixing the installer even after GA release.

When you say installer are you referring to the kernel upgrade installer? If you are on 2004 the kernel would be up to date, and running the upgrade with an up to date kernel seems to give the error that WSL is not installed.

I did not run the kernel upgrader after disabling and re-enabling WSL.

[ajensenwaud]

I had the same issue after upgrading to the latest Windows 10 (Enterprise) today. For those of you who are struggling to extract the MSI file from the command line or using Winzip, you can download 7zip instead and right-click extract. It works well.

[SquidPony]

I had the same issue and moving the unzipped contents did not resolve the issue for me.

Uninstalling Ubuntu, Deactivating the wsl feature, and reactivating and reinstall worked. (System reboots between each step)

The only "weird" thing in my setup is that I don't have my storage/location settings to C: drive, in case that matters to figure it out (if it's still getting looked at)

Ubuntu 20.04 as well, in case that matters.

[KayLeung]

@717009629,

If you don't mind, this issue should be re-opened. Upstream has not fixed this bug yet.

[YoungStoney]

Download the Linux kernel update package

Please download the latest WSL2 Linux kernel update package for x64 machines.

Note;
If you're using an ARM64 machine, please download the ARM64 package instead.
Install the Linux kernel update package

To install the Linux kernel update package:

1. Run the update package downloaded in the previous step.
2. You will be prompted for elevated permissions, select ‘yes’ to approve this installation.
3. Once the installation is complete, you are ready to begin using WSL2!

[tigercosmos]

same problem. I've tried all methods above but still fail.

Installing, this may take a few minutes...
WslRegisterDistribution failed with error: 0x80070057
Error: 0x80070057 The parameter is incorrect.    

[LeonardoSSev]

Use ZIP to extract wsl_update_x64.msi to any folder. Copy FID_LXSS_KERNEL from extracted location to C:\Windows\System32\lxss\tools\ and rename this file to "kernel"
After this wsl2 works.

That really worked for me! Thanks a lot. I've been trying just reinstalling the .msi kernel updating file but I was getting the message to install de kernel update every time. Thanks a lot. These steps for extracting the .msi and manually "installing" on the lxss folder helped me.

**Download the Linux kernel update package**

请下载适用于x64计算机的最新WSL2 Linux内核更新程序包。

注意;
如果您使用的是ARM64计算机，请改为下载ARM64软件包。
