今日、Ubuntu 20.04 LTSデスクトップシステムを更新しようとすると、次のエラーが発生しました。

Reading package lists... Error!
E: Encountered a section with no Package: header
E: Problem with MergeList /var/lib/apt/lists/ny-mirrors.evowise.com_ubuntu_dists_focal_universe_binary-i386_Packages
E: The package lists or status file could not be parsed or opened.GraphicalSynapticパッケージマネージャーで再試行しました。しかし、運がない！同じエラーが発生しました！
これは、UbuntuおよびDebianベースのシステムでよくある問題の1つです。
出力を少し注意深く読んだ後、パッケージリストまたはステータスファイルが何らかの理由で破損していることがわかりました。そのため、解析できませんでした。
不思議に思う人のために、ステータスファイルにはインストールされたdebパッケージに関する情報が含まれています。この問題は、破損したパッケージリストとステータスファイルを削除し、以下の説明に従って再生成することで解決できます。
Ubuntuで「パッケージのないセクションに遭遇しました：ヘッダー」エラーを修正
ステップ1。 まず、コマンドを使用して破損したパッケージリストを削除します：
$ sudo rm /var/lib/apt/lists/* -vf上記のコマンドは、Ubuntuシステムからすべてのパッケージソースリストを削除します。
これが私のUbuntu20.04LTSデスクトップからの出力例です：

$ sudo apt updateこれには、インターネットの速度によって異なりますが、しばらく時間がかかります。我慢して！
ステップ3。 パッケージリストが再生成されたら、次のコマンドを1つずつ実行して、完全な更新を実行します。
$ sudo apt update$ sudo apt upgrade$ sudo apt dist-upgradeステップ4。 Ubuntuシステムを更新した後、パッケージキャッシュをクリアします：
$ sudo apt autoclean$ sudo apt autoremoveステップ5。 最後に、開いているすべてのプログラムを閉じて、システムを再起動します。
$ sudo reboot問題はもう解消されているはずです。
ステップ6： それでも同じエラーが表示される場合に備えて、ステータスファイルを削除し、次のコマンドを使用して再構築します。
$ sudo rm /var/lib/dpkg/status$ sudo touch /var/lib/dpkg/status$ sudo apt updateシステム全体の更新を実行し、aptキャッシュをクリーンアップしてから、システムを再起動することを忘れないでください。
