メインストアリストファイルが削除されたようです。
次のコマンドは、/etc/apt/sources.listダウンロードしたUbuntu 18.04 LTSイメージファイルから取得した元のデフォルトファイルを提供します。
sudo echo -e "# Sources.list obtained directly from the downloaded Ubuntu iso image file\ndeb http://archive.ubuntu.com/ubuntu/ bionic main restricted\ndeb http://security.ubuntu.com/ubuntu/ bionic-security main restricted\ndeb http://archive.ubuntu.com/ubuntu/ bionic-updates main restricted" > /etc/apt/sources.list
デフォルトのストレージソースファイルを作成したら、次のものを更新する必要がありますapt-cache。
sudo apt-get update
この時点で、一部のPPAがプライマリストアと競合しているかどうかによって、エラーメッセージが表示されることがあります。ストレージの問題を解決する前に、すべてのPPAを無効にすることをお勧めします。ただし、さまざまなPPAからインストールされているソフトウェアの中には、公式のUbuntuよりも最新のライブラリが必要な場合、エラーが発生する可能性があります。
更新中にエラーが発生しない場合は、おそらく大丈夫でしょう。ただし、以下の制限の少ないリポジトリのリストを有効にする必要があります。コンテンツを/etc/apt/sources.list次のリポジトリのリストに置き換えることができます。
