I'm not sure what to do to reset the wsl environment I had it working with wsl 1.

I have the same error, I tried removing WSL, restarting, re-enabling WSL from nothing, upgrade to 2, same error again.

[MojoVampire]

Same error. I had WSL on my old machine, decided to start fresh on my new laptop (never used WSL at all on it), got the same error, at the same step.

Hello guys. I tried to install Kali Linux on my laptop (thanks to Microsoft Store), I thought "it will be easier". But isn't
I have had many problems, but finally I have the system installed. The problem is that I have version 1 and I need version 2. When i connect to remote system, I log in with my account on Kali Linux, but the screen keeps on black. I think that it is because off the WSL version. I went to the microsoft page and download the lastest version (https://aka.ms/wsl2kernel). But when I start it, it doesn't work.

HERE THE ERROR ========> The installer encountered an unexpected error while installing this package. This may indicate a problem with this package. The error code is 2502.

I didn't mention that I checked the box on Windows Features =====> WSL

Im not sure but this issue is open for another issue, I would recommend opening another issue.

[Itssuso17]

A lot of issues... What did you mean? Another task? haha

I'm saying the issue that we are discussing is not related to your issue and you shouldn't post unrelated issues in this thread.

[richtong]

Yikes I have the same problem. Googling does not reveal anything more than this issue. Same configuration. haad WSL1 installed as well

Virtualization is enabled in BIOS and ran that dism command
Windows 2004 OS Build 1904.450

I have Windows Home on this machine, but the FAQ indicates that is supported
https://docs.microsoft.com/en-us/windows/wsl/wsl2-faq

Help!

please refer the MS links and upgrade the WSL kernel then rerun the wsl set-version command should be fine !

Glad to be heard and feedback

ok i did the kernel upgrade and it now says, the same message but without the error code, so didn't work for me. Sent via Superhuman ( https://sprh.mn/[email protected] )

[MojoVampire]

@richtong: I got the same message without the error code, but when I went and installed Alpine Linux for WSL, it properly set it up as version 2, so I think it worked just fine. My problem is solved.

Error: 0x1bc here means: WSL 2 requires an update to its kernel component. For information please visit https://aka.ms/wsl2kernel. I think your display language or local setting is not English, and that's why you see the error code other than message itself.

It's easy to verify if kernel exists by command dir %SystemRoot%\system32\lxss\tools\kernel. If kernel doesn't exist, please install it by https://aka.ms/wsl2kernel
If you download and installed the .msi successfully, but you still didn't see kernel file in %SystemRoot%\system32\lxss\tools. It's possible that you didn't install the .msi with admin. Uninstall it and reinstall it admin permission.

Although wsl --set-default-version 2 with this error, actually the default version is changed to 2 already. When you install the distro from store, it will see it's version 2. Of course, because kernel is missing, you still not able to launch the distro and complete the setup process.

Installing the kernel worked for me, thanks! Maybe implement that as an error message or at least on the WSL website as an error code that is documented (hence why I chimed in on this post since there was no other documentation for it)

Thanks @licanhua

[ksolo]

The kernel install also worked. Thank you! closing this ticket now.

[licanhua]

Agree it's not well documented. This is a bug and I think it is fixed in newest Windows.
I created PR 835 to update the document.

[TanveshT]

@licanhua Is there a way to check the WSL version just to confirm?

Edit: Got it wsl -l -v

[vanillamice]

Tried re-installing the kernal,it just gives me this message "This update only appiles to machines with the windows subsystem for linux" even tho i have wsl 1 and it's functional.

[vservin]

I already have installed ubuntu wsl 1 and I wanted to upgrade, so attempting to enter wsl --set-default-version 2 was showing:

> wsl --set-default-version 2
Error: 0x1bc
For information on key differences with WSL 2 please visit https://aka.ms/wsl2

I attempted upgrading the kernel from https://docs.microsoft.com/en-gb/windows/wsl/wsl2-kernel but the output changed to

> wsl --set-default-version 2
For information on key differences with WSL 2 please visit https://aka.ms/wsl2

basically the same with no error code.
The fix
I ran the recommended command but for a specific distro like this:

> wsl --set-version ubuntu 2
Conversion in progress, this may take a few minutes...

I hope this helps!

I am using kali Linux what do I put instead of ubuntu

I am using kali Linux what do I put instead of ubuntu

The distro name for Kali is kali-linux so the command should be

> wsl --set-version kali-linux 2

I'm not sure what to do to reset the wsl environment I had it working with wsl 1.

I have the same problem, here's my solution:

check if you have one or more versions: On command prompt wls -l -v

Now convert all versions to wsl 2: On command prompt wsl --set-version <NAME> 2

That works for me.

See ya.

@1josh13 the kernel file exists but stil i'm getting this issue( The file path specified does not exisit). Any fixes?

[licanhua]

@nagarajcruze Please create new issue and submit logs. This is a generic error and most of time, it's missing kernel. It's hard to know what's the root cause without log since you already have kernel.

[nagarajcruze]

@licanhua how to take logs?

[licanhua]

https://github.com/microsoft/WSL/blob/master/CONTRIBUTING.md#8-collect-wsl-logs

[nagarajcruze]

@licanhua this link doesn't seems to show ways to generate logs, instead just to screen record?

I downloaded new Ubuntu version from Microsoft Store and installed. That helped me. Please look guide below. ;)

[Alexie81]

Hello !
It's clear: a team of incompetents who don't know how to make a virtual machine and a linux on windows properly.
At least, why don't you answer the questions ?!
If you can answer my question, I withdraw my comment:
I installed wsl kernel, but when I tell him where it is, he can't find it:

dir% SystemRoot% \ system32 \ lxss \ tools \ kernel
dir: Cannot find path 'C: \ WINDOWS \ system32 \% SystemRoot% \ system32 \ lxss \ tools \ kernel' because it does not exist.
At line: 1 char: 1
+ dir% SystemRoot% \ system32 \ lxss \ tools \ kernel
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo: ObjectNotFound: (C: \ WINDOWS \ syst ... ss \ tools \ kernel: String) [Get-ChildItem], ItemNotFound
   Exception
    + FullyQualifiedErrorId: PathNotFound, Microsoft.PowerShell.Commands.GetChildItemCommand

and I follow all the steps, but when I give wsl --set-default-version 2, I no longer have kali-linux installed. Why is this happening ?
And I want to remind you that you may think me wrong: I HAVE ACTIVATED EVERYTHING NECESSARY !!!!!!!!!!!

[mastery-shital-pacharne]

wsl --set-version Ubuntu-20.04 2
wsl --set-version Ubuntu-18.04 2

just check which version you are installing on
and it will work

[nagarajcruze]

@mastery-shital-pacharne Thanks for the help but I did a reset to my laptop and fixed it.

OS: Windows 11
Summary: This problem seems to come back with Windows 11.

Fixing WSL 1 and Upgrading to WSL 2

It seems if you start with installing a Linux distro in WSL 1 (the default), you need to do some extra steps to clean up.

To get things to work: - Download the kernel update libraries from the Microsoft website:
https://learn.microsoft.com/en-us/windows/wsl/install-manual#step-4---download-the-linux-kernel-update-package

After this step, WSL should start working.
Access Bash and update WSL and the distro to WSL v2:

wsl --set-default-version 2
wsl --set-version <distro_name> 2

To verify that the upgrade was successful, run the following command:

wsl --list -v

You should see the distro listed with a version of 2.

Note: If you prefer to start with a fresh install of Windows and upgrade to WSL v2, that is also an option.
