Could not determine data directory

Error message

Could not determine data directory

What it means

upscale::install() first resolves the managed tools directory via managed_dir(). If that returns None — meaning the application could not locate or create its per-user data directory — install aborts with this error before contacting GitHub. It indicates the environment lacks a resolvable data directory (e.g. no HOME/XDG_DATA_HOME/APPDATA).

Solutions

1. Set the appropriate environment variable (HOME on Linux/macOS, APPDATA on Windows) before launching the app
2. Run the app as a normal desktop user rather than a service account without a home directory
3. Check managed_dir()'s implementation to see which directories it probes and create the expected directory manually
4. Pass an explicit data directory through configuration if the code supports overriding it

Example fix

// before
HOME= ./myapp
// after
export HOME=/home/user && ./myapp

fn has_data_dir() -> bool {
    std::env::var_os("HOME").is_some()
        || std::env::var_os("APPDATA").is_some()
        || std::env::var_os("XDG_DATA_HOME").is_some()
}

match upscale::install(&progress).await {
    Err(e) if e.to_string().contains("data directory") => {
        eprintln!("Configure HOME ou APPDATA e reinicie.");
    }
    other => other,
}

When it happens

Trigger: Calling install() on a system where managed_dir() returns None: HOME unset, XDG_DATA_HOME pointing nowhere writable, no APPDATA on Windows, or the data root could not be determined at all.

Common situations: Running inside a container or systemd service without HOME set; portable deployments with stripped environment; nonstandard OS layouts; CI sandboxes.
