Silent failure when /index.json is missing during initialization and remote URL is uninitialized

[ndrufin-crto]

Contexte

During the initialization phase, if no configuration exists, the code attempts to open /index.json. The error is not caught and the operation fails silently.

Description

This issue is located in the initBackend function within cmd/root.go. The error is reported by the PackageSource.InitialInstallCommands function. When the error is caught, it outputs:

Failed to initialize package source default: install failed for the following reasons: [cannot get remote packages: open /index.json: no such file or directory]

However, this error is not caught and the return code remains 0.

The underlying cause is that the error only happens if RemoteBaseURL is not initialized in the command-launcher config, leading to a missing remote URL during init.

Suggested Fix

• Detect when the command-launcher config remote URL (RemoteBaseURL) is not initialized and prevent running initial install.
• Catch and handle errors during initialization and provide a clear, user-friendly error message.
