WSL distro (Ubuntu) missing on the Windows Server 2022 Image created with Windows-2022.pkr.hcl

[Codes-Lab]

Hi all,

I am new to the community and just started to work with Packer. I am currently trying to build a Windows-2022 image with Packer having WSL and Ubuntu as distribution installed. Surprisingly the image creation until the last step prints out that Ubuntu is installed as the default distro but somehow I cannot see the Ubuntu distro when I created the VM from the image although WSL is installed and working.

Edit: I updated the windows-2022.pkr.hcl template to install the WSL and ubuntu with the following custom scripts.

Install-Binary -Type MSI -Url "https://wslstorestorage.blob.core.windows.net/wslblob/wsl_update_x64.msi"
 Write-Host "Setting WSL default version to 2"
 wsl --set-default-version 2

 # Installing Ubuntu
 $ubuntuAppxPath = Invoke-DownloadWithRetry "https://aka.ms/wslubuntu2004" -Path "${env:SystemDrive}\Users\${env:INSTALL_USER}\$fileName"
 Write-Host "ubuntuAppxPath is : ${ubuntuAppxPath}"

 Write-Host "Expanding Ubuntu bundle"
 [string] $tempName = [System.Guid]::NewGuid()
 $ubuntuExpandPath = "${env:SystemDrive}\Users\$env:INSTALL_USER\Ubuntu\$tempName"
 Expand-Archive $ubuntuAppxPath $ubuntuExpandPath

 Write-Host "Expanding ubuntu application"
 $ubuntuAppx = Get-Item -Path $ubuntuExpandPath/*_x64.appx
 Move-Item $ubuntuAppx $ubuntuExpandPath/ubuntu.zip
 Expand-Archive $ubuntuExpandPath/ubuntu.zip $ubuntuExpandPath -Force

 Write-Host "Installing Ubuntu"
 & $ubuntuExpandPath\ubuntu.exe install --root
 if($LASTEXITCODE -ne 0) {
    Write-error "Failed to install Ubuntu 2004 under wsl"
 }

Ubuntu was downloaded from https://aka.ms/wslubuntu2004 to a folder installer and it was under Users and I could the installed files under this folder in the VM created from Image.

Logs from the image creation:

Does anyone have faced a similar issue or am I dumb to understand it, does someone have any idea how to fix it?

More Information: It seems the registry entry for the Lxss default Distribution went missing in the created image.
Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Lxss

I learned that WSL distribution (in my case Ubuntu) installation is user-specific, I created a new user and used the same user in my pipelines which fixed the issue for me. So this is not a problem for me anymore.
