「apt-get update」は多くの[Ign]エラーを発生させます-それは問題ですか？

Question

もう一度Sudo apt-get updateを実行しましたが、出力にIgnではなくHitで始まる行がたくさんあると思いました。

私はそれが何を意味するのか疑問に思って buntuに尋ねる と スーパーユーザー について調査しましたが、彼らは矛盾した答えを持っていました。チャットで@Sethと議論し、論理的な思考を交わした後、次のような結論に達しました。

• Hitは、「このパッケージインデックスリストはすでにダウンロードされており、最新のものです」という意味です。
• Ignは、「エラー404（見つかりません）のため、このインデックスリストをダウンロードできませんでした。ただし、翻訳が見つからないため、エラーは無視できますが、パッケージはデフォルトの言語で利用可能です。 」

私の質問は次のとおりです：

• 構成に非常に多くの利用できないリポジトリがリストされているのはなぜですか？現在23個のIgn-エントリがありますが、そのうち5個はインストールDVDに属します。
• それらは何らかの損害を引き起こしますか（更新プロセスの速度低下、リストの欠落など）？
• それが悪い考えではない場合、どうすればそれらを取り除くことができますか？

Answer 1

構成に非常に多くの利用できないリポジトリがリストされているのはなぜですか？現在23のIgnエントリがありますが、そのうち5つはインストールDVDに属します。

翻訳が欠落していても、リポジトリは使用できません。 InReleaseファイルがない場合もありますが、サーバーがRelease{,.gpg}ファイルを提供している場合は問題ありません。

それらは何らかの損害を引き起こしますか（更新プロセスの速度低下、リストの欠落など）？

少し。 Aptは複数の要求に対して単一の接続を使用するため、一部の要求は遅延しますが、大きな違いはないと思います。適切なRelease{,.gpg}も利用可能であれば、リポジトリは正常に機能します。

それが悪い考えではない場合、どうすればそれらを取り除くことができますか？

翻訳の場合： aptの翻訳エントリを削除するにはどうすればよいですか？

InReleaseの場合、そのようなオプションはありません。 この機能リクエストは2015年に修正されませんでした ：

とにかく、4年後、私たちはすべてInReleaseの新しい世界秩序を受け入れ、実際にコードが実際に変更され、少なくとも最初にInReleaseを試すことを避けるのがさらに難しくなりました。
