Add this to a PowerShell script or use a Batch script with tools and in places where you are calling directly to Chocolatey. If you are integrating, keep in mind enhanced exit codes.

If you do use a PowerShell script, use the following to ensure bad exit codes are shown as failures:

choco upgrade wsl-ubuntu-2004 -y --source="'INTERNAL REPO URL'" 

Write-Verbose "Exit code was $exitCode"
$validExitCodes = @(0, 1605, 1614, 1641, 3010)

Package parameters

  • /InstallRoot:true - whether to set the default user as root. Defaults to false

Example: choco install wsl-ubuntu-2004 --params "/InstallRoot:true"


  • This package checks to see if WSL is installed before downloading the distro archive file. If this check fails, the install will fail.
  • Important: Install wsl or wsl2 then restart before attempting to install this package. A dependency was not declared since installing this package on a system where WSL wasn't installed before will always fail since WSL requires a restart before it can be used.

In cases where actual malware is found, the packages are subject to removal. Software sometimes has false positives. Moderators do not necessarily validate the safety of the underlying software, only that a package retrieves software from the official distribution point and/or validate embedded software against official distribution point (where distribution rights allow redistribution).

Chocolatey Pro provides runtime protection from possible malware.
