VSCode Remote-WSL无法打开报错‘Multi distro not supported’如何解决？

Hey, let’s work through this connection problem you’re hitting. That "Multi distro support requires a newer version of wsl" error pops up even with just one distro because your Windows 10 1903 ships with an older WSL version that can’t keep up with the latest Remote-WSL extension features. Here are actionable solutions to get things working:

Option 1: Update WSL 1 to its latest compatible version (no system upgrade needed) #

• Fire up PowerShell as an administrator, then run this to check your current WSL status:
  wsl --status
• If it confirms you’re on WSL 1, grab the official WSL update package:
  • Try running this command first (it might work directly on 1903):
    wsl --update
  • If that command isn’t supported, manually download the Windows Subsystem for Linux Update Package from Microsoft’s site, install it, then restart your PC.
• After rebooting, go back to your Ubuntu terminal and run code . again—this should resolve the version mismatch.

Option 2: Upgrade to WSL 2 (highly recommended for better compatibility) #

Windows 10 1903 does support WSL 2, you just need to enable the required features:

1. Open PowerShell as admin and run this to turn on the Virtual Machine Platform:
   dism.exe /online /enable-feature /featurename:VirtualMachinePlatform /all /norestart
2. Restart your computer to apply the change.
3. Back in admin PowerShell, set WSL 2 as the default and switch your Ubuntu distro to use it:
   wsl --set-default-version 2
wsl --set-version Ubuntu 2
4. Restart your WSL session, then try code . again. The Remote-WSL extension plays much nicer with WSL 2.

Option 3: Downgrade the Remote-WSL extension to an older compatible version #

If you’d rather not touch your WSL setup, try rolling back the extension:

• In VSCode, find the Remote-WSL extension in the extensions panel. Click the gear icon next to it and select Install Another Version...
• Pick an older release (anything from 2022 or earlier should work with WSL on 1903), install it, restart VSCode, then test the connection again.

Quick Additional Checks #

• Make sure your Ubuntu distro is fully updated: Run sudo apt update && sudo apt upgrade -y in your Ubuntu terminal, then try connecting again.
• Verify VSCode itself is up to date: Click the settings icon in the bottom left, select Check for Updates, and install any available updates.
