重複の可能性：
apt-get更新リストのサイズが大きすぎます
クリーン後 12.04（リリース候補）をインストールし、今日までのすべての更新とアップグレードを受け入れると、sudo apt-get updateが見つかりました 常にMB範囲（約12 MB）の情報をフェッチしますが、sudo apt-get upgrade ほとんどの場合、ダウンロードするものはありません。
私が見る最大の3つのフェッチは次のとおりです。
http://archive.ubuntu.com precise/universe Sources [5,019 kB]
http://archive.ubuntu.com precise/main i386 Packages [1,274 KB]
http://archive.ubuntu.com precise/universe i386 Packages [4,796 KB]
sudo apt-get updateはかなり確信しています フェッチは11.10ほど大きくはなく、1MBを超えることはめったにありませんでした。
私の質問はこれです：12.04が最近のものであるという理由だけでこれらの大規模なフェッチですか、それともこれらの大規模な更新が標準になるのでしょうか？

apt.confのdeb-srcを無効にしました マイクごとの行数は何でも答えます。これにより、あなたと同じように、最大6MBになりました。
次に、aptがパッケージ情報を取得しているときに、192.168.1.3（squid-deb-proxy）を通過していることに気付きました。 サーバー（11.10を実行します。まだアップグレードに取り掛かっていません）。 squid-deb-proxy-clientのアンインストール クライアントからの情報のダウンロードサイズが通常に戻りました。
編集：ああ、それは以前の振る舞いに戻りました。また、Macの仮想マシン（安定したリリースがリリースされた日のフレッシュインストール）もチェックしました。これは時々起動します。パッケージの更新情報も大きなダウンロードです。このソリューションが機能しないことを文書化するために、この回答はそのままにしておきます。それを超えて、私は立ち往生しています。
