FileNotFoundError: [Errno 2] No such file or directory: '/tmp/fletd-0.3.2-linux-amd64.tar.gz'

報告された NixOS 環境で flatpak run org.openandroidinstaller.OpenAndroidInstaller を使って、まず失敗を再現します。/app/lib/python3.10/site-packages/flet/flet.py、特に _download_fletd() と、openandroidinstaller.py のエントリーポイント startup() を確認します。ダウンロードのタイムアウトによって、二次的なファイル欠落エラーが発生しなければ完了です。
