Auto-update failed: {:#} {}

Error message

Auto-update failed: {:#}

{}

What it means

run_install_script performs the actual auto-update install and records telemetry about the attempt; on failure it wraps the underlying error chain with `{:#}` (all anyhow sources) plus a reinstall_hint containing manual reinstall instructions for the current installer and channel. This is the top-level wrapper, so the root cause is in the nested error text, and the appended hint gives the manual fallback.

/// Apple Silicon host (Rosetta) selects `aarch64`, so every update path —
/// interactive `grok update`, background `--auto` children, the leader's
/// hourly converge, and forced minimum-version installs — converges to the
/// native build instead of perpetuating the translated one. This mirrors
/// install.sh's `hw.optional.arm64` probe; without it, a lingering x86_64
/// process would reinstall x86_64 right over a fresh native install.

Solutions

1. Read the `{:#}` portion of the message for the root-cause error chain first
2. Follow the reinstall_hint's manual reinstall commands to recover immediately
3. Check write permissions on the install directory or reinstall with elevated/instructions-based install
4. Retry after checking network/proxy issues if the root cause was download-related

Example fix

// before
result.map(|_| ()).map_err(|e| {
    anyhow::anyhow!("Auto-update failed: {:#}\n\n{}", e, reinstall_hint(installer, &update_config.channel))
})
// after
result.map(|_| ()).map_err(|e| {
    eprintln!("auto-update failed: {:#}; falling back to manual reinstall", e);
    anyhow::anyhow!("Auto-update failed: {:#}\n\n{}", e, reinstall_hint(installer, &update_config.channel))
})

// pre-check install dir writability and artifact reachability
let dir = install_dir();
if !is_writable(&dir) { eprintln!("install dir not writable: {}", dir.display()); }
// HEAD the artifact URL before running the update

match ensure_latest_on_disk(&cfg).await {
    Err(e) => {
        eprintln!("{e:#}"); // walk the full source chain for the root cause
        eprintln!("falling back to manual reinstall per hint");
        run_manual_reinstall()?;
    }
    Ok(()) => {}
}

When it happens

Trigger: Calling run_update or ensure_latest_on_disk when the install script fails — download integrity failure, script execution error, permission problem writing the install location, or unsupported platform/installer combination.

Common situations: No write permission to the install directory (e.g. system-managed locations); a partially downloaded or corrupted artifact failing checksum; proxy/firewall blocking the artifact download; Rosetta/Apple Silicon edge cases selecting the wrong installer.
