epub2pdfプラットフォームに依存しないプログラムです。 Javaに基づいており、依存関係なしにマイコンピュータでシームレスに実行されます。
しかし、奇妙なことに、プログラムが正常に動作するには、アクティブなインターネット接続が必要です。最初はこの事実に気付かなかったが、そのプログラムのウェブサイトには、そのプログラムが「オンライン」コンバータのフロントエンドにすぎないという内容は記載されていません。
これは普通ですか？
これは私生活の侵害ではありませんか？
このプログラムがなぜ必要外部サーバーへのHTTP接続を設定しますか？
また、このプログラムはDebian / Ubuntuリポジトリでは使用できません。
これはこの質問に関連していますか？
誰かが代替案を提案できますか？
インターネット接続なしで実行したときに発生するエラーは次のとおりです。
