Windows 10: Resolving WslRegisterDistribution error 0x80370102 when installing Linux Distro for WSL 2?

# Encountering WslRegisterDistribution error 0x80370102 when installing Linux Distro for WSL 2


I am currently on the `Windows 10 Pro Insider Preview build 18922.rs_prerelease`, and am trying to install a Linux distribution to access via Windows Subsystem for Linux (2). I have tried this for both the Ubuntu and Debian distros and have encountered the same error in each.


I have successfully downloaded both distros from the Microsoft store, but when I try to first "run" the Ubuntu or Debian "app" the respective console comes up and prints the following text:


Installing, this may take a few minutes...
WslRegisterDistribution failed with error: 0x80370102
Error: 0x80370102 The virtual machine could not be started because a required feature is not installed.

Press any key to continue...


Pressing a key at this point automatically exits the console.

## Additional information:


- Using the `wsl -l` command shows no installed distros.

- I do have Hypervisor installed and running `bcdedit` does show that `hypervisorlaunchtype` is set to `Auto` in the `Windows Boot Loader` section.

- I did previously have Ubuntu installed and working under WSL 1 before switching to the Windows Insider Program Fast Ring and gaining access to WSL 2, but I was encountering another issue when trying to have it use WSL 2. After trying to use the command `wsl --set-version Ubuntu 2` I was met with a request to "Enable the Virtual Machine Platform". I had already run `Enable-WindowsOptionalFeature -Online -FeatureName VirtualMachinePlatform` prior, according to the official microsoft tutorial here https://docs.microsoft.com/en-us/windows/wsl/wsl2-install, but for good measure I did it again and got the same error, and Ubuntu was still on version 1 (I haven't explicitly mentioned it but I was restarting/shutting down when requested/suggested by windows and tutorials, so I don't believe me not restarting is a cause). In hopes to find a workaround, I ended up uninstalling Ubuntu and hoping I could reinstall it and have it obey the default defined by the `wsl --set-default-version 2` command (suffice it to say, this did not go as I'd hoped).

- This might be an unrelated issue, but when I initially attempted reinstalling Ubuntu, the Microsoft store had a bit of a fit and could not complete the download- encountering an 'unknown error'. I did a restart, tried again, and got the same error, but then after telling it to 'try again' it succeeded. I had no such issues installing Debian from the store.

## Suggestions Welcome


I've searched for a bit and can't find mention of this error code in particular anywhere else.

In addition, is there anywhere I can look up/access these error codes in any sort of documentation? Ideally so I can make a better informed work-around attempt before bothering you all on here.

All help is appreciated!

Alternatives to using Windows Store to install Linux distro on WSL

I just wanted to ask what alternatives there are to using the Windows 10 to install Linux distros on WSL.

Also, it seems like Ubuntu 19 isn't available for the WSL. Is there a chance that we'll be able to install it when WSL2 is released? And I'd like to get the latest non-LTS version if possible (though it's alright if it's not possible too).

 

Alternatives to using Windows Store to install Linux distro on WSL

Thanks for the reply.

I got the distro named "Ubuntu" from the Store. I already had another one but there were problems with it (I installed Node but trying to use it gave me an error saying that there's no such command and that I should install it using Apt), so I wanted to
get a fresh distribution of Ubuntu on the WSL to see if that would solve the issue.
