Using WSL2 Part 5 (Installing Multiple Instances of the Same Distribution, Ubuntu 22.04)
管理人Introduction
In this post, I installed a second instance of the same Ubuntu version on WSL2.
I didn't want to mess up my original Ubuntu 22.04 environment on WSL2, so I was looking for a way to install it separately. When working with AI software, I often run into trouble with conflicting dependencies for CUDA or Conda. I want to be able to switch between entire Ubuntu environments to avoid these issues.

Importing the Distribution
Initially, I tried to install Ubuntu 20.04.
▼There are Ubuntu 20.04 images on the following page:
https://cloud-images.ubuntu.com/releases/focal/release
However, the images on this page are not specifically for WSL, so I couldn't install them. My attempt failed.
▼I tried installing "ubuntu-20.04-server-cloudimg-amd64.tar.gz."
▼The subsequent steps failed.
A WSL-specific image file is required.
▼Navigating to the parent directory reveals a list, and the "wsl" folder was there.
https://cloud-images.ubuntu.com
Only Ubuntu 22.04 and later versions were available.
▼This time, I downloaded from the following link:
https://cloud-images.ubuntu.com/wsl/jammy/current
▼I downloaded "ubuntu-jammy-wsl-amd64-ubuntu22.04lts.rootfs.tar.gz."
Now, I'll import the downloaded file.
▼WSL2 commands are listed on this page:
https://learn.microsoft.com/ja-jp/windows/wsl/use-custom-distro#import-the-tar-file-into-wsl
Launch PowerShell with administrator privileges and import using the following command format:
wsl.exe --import <Distro> <InstallLocation> <FileName> [Options]In my environment, I executed it as follows. Note that although it's Ubuntu 22.04, I named it "Ubuntu2004_GS" by mistake due to a leftover from a previous test. I'll change the name later.
mkdir W:\Ubuntu2004_GS
wsl --import Ubuntu2004_GS "W:\Ubuntu2004_GS" "C:\Users\mgs_1\Downloads\ubuntu-jammy-wsl-amd64-ubuntu22.04lts.rootfs.tar.gz"▼It was imported without any issues.
You can check if it has been added with the following command:
wsl -l -v▼It has been added as "Ubuntu2004_GS."
You can activate the environment with the following command:
wsl -d Ubuntu2004_GS▼I was logged in as root.
At this point, the username and password setup screen did not launch, and it seemed I was logged in as root by default.
If you fail, you can delete the files and unregister it to try the installation again.
wsl --unregister Ubuntu2004_GS▼Previously, I also unregistered and then reinstalled in a similar way.

Launching the Terminal
I was logged in as root earlier, but I want to register a user so I can log in properly. After activating the Ubuntu environment, I executed the following commands:
adduser <username>
usermod -aG sudo <username>▼I was also prompted to enter a password.
▼I confirmed that a folder with the registered username exists in the /home directory.
I edited /etc/wsl.conf to set the default user.
sudo nano /etc/wsl.conf▼I added "default=" under the [user] section.
After this, I reopened PowerShell and reactivated the Ubuntu environment, and it logged me in as the registered user.
▼The directory was set to the Windows one, but executing the "cd" command without arguments moved me to the user's home directory.
▼It is indeed Ubuntu 22.04.
Creating a Copy and Renaming
Embarrassingly, I had named it "Ubuntu2004" even though it was Ubuntu 22.04, so I changed it. I handled this by exporting the current environment with a WSL2 command and importing it under a different name.
First, I exported the tar file with the following command:
wsl --export Ubuntu2004_GS ubuntu2004_gs.tar▼It executed without any issues.
▼A tar file was created in the execution directory.
Now, import it with the following command:
wsl --import Ubuntu2204_GS W:\Ubuntu2204_GS ubuntu2004_gs.tar▼It was also added to the list.
▼It launched properly as Ubuntu 22.04.
I unregistered and deleted the environment with the incorrect name.
wsl --unregister Ubuntu2004_GS▼The contents of the folder were also empty.
Creating a Shortcut
Normally, if you press the Windows Start button, there's an application ready to launch the Ubuntu terminal.
▼It looks like this.
I couldn't find one this time, so I created a shortcut on the desktop.
▼Right-clicking on the desktop shows "Shortcut" under the "New" menu.
▼Create the shortcut based on the command used to activate the Ubuntu environment.
▼The shortcut has been added! Double-clicking it opens the terminal in a logged-in state.
Note that it was also added to the terminal's dropdown menu, so you can enter the terminal from there as well.
▼Selecting it started me in the user directory.
Finally
Up until now, I had only used one instance of each Ubuntu version, but now I can build and use multiple environments.
I'm planning to use another PC to build the 3D Gaussian Splatting environment I've been testing recently, following this verification.
▼I've also been developing a rather niche Node-RED node that uses WSL2 to execute commands in the Ubuntu environment, and I think I can improve it into a node that can switch between different environments.
