Can Not Connect VSCode to WSL2 Running Ubuntu-22.04? We’ve Got You Covered!

Are you tired of staring at the frustrating “can not connect” error message while trying to connect your VSCode to WSL2 running Ubuntu-22.04? Well, buckle up, friend, because we’re about to take you on a journey to troubleshoot and fix this annoying issue once and for all!

What’s the Deal with WSL2 and VSCode?

Before we dive into the solution, let’s quickly cover the basics. WSL2 (Windows Subsystem for Linux 2) is an incredible feature that allows you to run a Linux environment directly on Windows. It’s a game-changer for developers, enabling them to work on Linux-based projects without leaving the comfort of their Windows machine.

VSCode, on the other hand, is an extremely popular code editor that’s widely used by developers worldwide. Its seamless integration with WSL2 makes it an ideal choice for working on Linux-based projects. However, like any complex system, it’s not immune to issues, and the “can not connect” error is one of the most common problems you might encounter.

Why Can’t VSCode Connect to WSL2 Running Ubuntu-22.04?

There are several reasons why VSCode might not connect to WSL2 running Ubuntu-22.04. Here are some of the most common culprits:

• Outdated WSL2 or VSCode versions: Make sure you’re running the latest versions of both WSL2 and VSCode. Outdated versions can cause compatibility issues that lead to connection errors.
• Incorrect WSL2 distribution configuration: The WSL2 distribution configuration might be incorrect or corrupted, preventing VSCode from connecting.
• VSCode settings issues: VSCode settings might be misconfigured, causing the connection to fail.
• Ubuntu-22.04 configuration issues: Ubuntu-22.04 might have configuration issues or missing packages that prevent VSCode from connecting.
• Firewall or antivirus interference: Firewalls or antivirus software might be blocking the connection between VSCode and WSL2.

Troubleshooting Steps to Fix the Connection Issue

Now that we’ve covered the possible reasons behind the connection issue, let’s get started with the troubleshooting steps to fix it:

Step 1: Update WSL2 and VSCode

Make sure you’re running the latest versions of WSL2 and VSCode:

wsl --update
code --version

Update WSL2 and VSCode if you’re not running the latest versions.

Step 2: Configure WSL2 Distribution

Check the WSL2 distribution configuration:

wsl --list --verbose

Make sure the Ubuntu-22.04 distribution is listed and set as the default distribution. If not, set it as the default:

wsl --set-default Ubuntu-22.04

Step 3: Configure VSCode Settings

Check the VSCode settings:

code --open-url "vscode://file/%USERPROFILE%/.vscode/settings.json"

Verify that the following settings are configured correctly:

"remote.WSL2.path": "/usr/bin/wslg",
"remote.WSL2.defaultDistribution": "Ubuntu-22.04",

Update the settings if necessary.

Step 4: Configure Ubuntu-22.04

Check the Ubuntu-22.04 configuration:

wsl

Verify that the following packages are installed:

sudo apt update
sudo apt install -y wslg

Install the wslg package if it’s not already installed.

Step 5: Disable Firewall and Antivirus Interference

Temporarily disable your firewall and antivirus software to see if they’re interfering with the connection:

# Disable firewall (Windows Defender)
Set-NetFirewallProfile -Profile Domain,Private,Public -Enabled False

# Disable antivirus software (temporary)

Try connecting VSCode to WSL2 again. If it connects successfully, re-enable your firewall and antivirus software, and then configure them to allow the connection.

Additional Troubleshooting Tips

If you’re still experiencing issues, try the following additional troubleshooting tips:

• Check the WSL2 logs: Run wsl --log to check the WSL2 logs for any errors or issues.
• Verify the VSCode Remote extension: Make sure the VSCode Remote extension is installed and enabled. You can check this by running code --open-url "vscode://extensions/remote";
• Try a different WSL2 distribution: If you’re using Ubuntu-22.04, try switching to a different WSL2 distribution, like Ubuntu-20.04 or Debian, to see if the issue persists.
• Reinstall WSL2 and VSCode: As a last resort, try reinstalling WSL2 and VSCode to start with a clean slate.
