"visudo -x"オプションを使用した後、sudoはありません。

visudo構文エラーについて警告したため、変更せずに終了しました。私はその中に新しいファイルを作成することにしました/etc/sudoers.d。残念ながら、私はマンファイルの概要に十分注意を払わず、それを投稿しませんでしたsudo visudo -x /etc/sudoers.d/jupyter（正しい引数では-fないはずです-x）。新しいファイルを作成するのではなく、私の設定をエクスポートしました。最終結果は次のとおりです。もはやsudoは必要ありません。

1. リカバリモードで再起動しなくてもリカバリできますか？
   • この方法私には適していません（ノーチラスを使用）
2. またvisudo、これはうまくいくべきですか？ （斜めではありませんが、意図された目的はユーザーを保護することです。そうですか？）ところで、どうしても輸出対象が適切かどうかは確認しないようですね。

Debian 8（32ビット）の使用
