当前平台不支持启动安装包

Error message

当前平台不支持启动安装包

What it means

launch_installer opens the downloaded update installer with a platform-specific command (Windows ShellExecute-style open, macOS `open` for DMG). The `#[cfg(all(not(windows), not(target_os = "macos")))]` fallback arm intentionally does nothing but bail: on Linux/BSD and other platforms there is no supported installer-launch mechanism in this code path.

Solutions

1. On Linux, skip the auto-launch step and instead run the downloaded installer/archive manually.
2. Add a Linux arm to launch_installer (e.g. make the AppImage executable and spawn it) if your fork targets Linux.
3. Gate the 'launch installer' UI action by platform so Linux users get a 'download complete, install manually' message.

Example fix

// before (caller)
perform_update(...)?; // implicitly launches installer
// after
if cfg!(any(windows, target_os = "macos")) {
    perform_update(...)?;
} else {
    download_update_only(...)?; // user installs manually
}

#[cfg(all(not(windows), not(target_os = "macos")))]
let can_auto_launch = false;
#[cfg(any(windows, target_os = "macos"))]
let can_auto_launch = true;
if can_auto_launch { perform_update(...)?; } else { show_manual_install_instructions(); }

if let Err(e) = perform_update(...) {
    if e.to_string().contains("当前平台不支持启动安装包") {
        open_downloaded_file_location(); // let user install manually
    } else { return Err(e); }
}

When it happens

Trigger: Calling perform_update → launch_installer on a non-Windows, non-macOS platform (e.g. Linux) after downloading the release asset; or a build where the platform cfg arms above were compiled out.

Common situations: Running the desktop manager on Linux and clicking 'update now'; CI containers on ubuntu images exercising the update flow; architectures where the matched platform_asset_rank picks a generic archive rather than a launchable installer.
