This test case imports a WSL image from a rootfs and runs it.
It requires a working Microsoft Windows 10 or higher installation with WSL2 enabled. Installing Windows and enabling WSL 2 is outside of the
scope of this test case.
To run this test you must download the image from http://cloud-images.ubuntu.com/
For example for latest focal image download:
http://cloud-images.ubuntu.com/focal/current/focal-server-cloudimg-amd64-wsl.rootfs.tar.gz
Open Windows Terminal or PowerShell and execute the test case below:
- Import the image in WSL
> wsl.exe --import <name of the distro> <location to unpack rootfs> <rootfs> [--version <version of WSL>]
For example:
> wsl.exe --import Ubuntu20.04.3 .\wsl\ .\Downloads\focal-server-cloudimg-amd64-wsl.rootfs.tar.gz --version 2
- Verify that the image has been imported by running the following command:
> wsl.exe --list --all --verbose

Ubuntu-Preview Stopped 2
Ubuntu-20.04 Stopped 2

- Check the the name used in previous command appears in the list.
- Launch the newly installed application
> wsl -d Ubuntu20.04.3
- Verify that you're inside the WSL instance and running the right distribution. For example run:
# lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 20.04.3 LTS
