how to solve this issue ?

The error "unable to find user codespace: no matching entries in passwd file" indicates a user permission issue in your dev container configuration.

Try these fixes:

1. Check your devcontainer.json for user settings:

{
  "remoteUser": "vscode",
  "containerUser": "vscode"
}

2. If using a custom Dockerfile, ensure the user exists:

RUN useradd -m -s /bin/bash vscode
USER vscode

3. Reset the codespace:

• Go to your codespace settings
• Click "..." menu → "Delete"
• Create a new codespace from scratch

4. Check for authentication issues:
The "Shell server terminated (code: 126, signal: null)" suggests a permissions problem. Try adding to your devcontainer.json:

{
  "postCreateCommand": "sudo chown -R vscode:vscode /workspaces"
}

5. If using a prebuild:
Prebuilds can sometimes cache bad configurations. Disable prebuilds temporarily and create a fresh codespace.
