Details for revision 1842 of testcase: WSL Import and run

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
NAME             STATE           VERSION
*Ubuntu          Running         2
Ubuntu20.04.3    Stopped         2
Ubuntu-Preview   Stopped         2
Ubuntu-20.04     Stopped         2
TestUbuntuWSL    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
Release:        20.04
Codename:       focal

Since the image has been installed directly and not with the distro launcher, you're logged in a root by default and have to create a first user manually.

# adduser ubuntu
Adding user `ubuntu' ...
Adding new group `ubuntu' (1000) ...
Adding new user `ubuntu' (1000) with group `ubuntu' ...
Creating home directory `/home/ubuntu' ...
Copying files from `/etc/skel' ...
New password:
Retype new password:
passwd: password updated successfully
Changing the user information for ubuntu
Enter the new value, or press ENTER for the default
Full Name []:
Room Number []:
Work Phone []:
Home Phone []:
Other []:
Is the information correct? [Y/n]

Add the newly created user to the sudo group:

# usermod -aG sudo ubuntu

Verify that you can switch to the new user

# su ubuntu
To run a command as administrator (user "root"), use "sudo <command>".
See "man sudo_root" for details.
$ whoami
ubuntu

Exit WSL. TypeCTRL+D twice until you're back to the PowerShell prompt.

Start a WSL session directly with the newly created user.

		> wsl -d Ubuntu20.04.3 -u ubuntu
		To run a command as administrator (user "root"), use "sudo <command>".
