Ubuntu-20.04 LTSは、国内の163ソース、Alibabaソース、Tsinghuaソース、およびZhongkeDayuanに置き換わるものです。

Ubuntu 20.04はUbuntuの8番目のLTSバージョンです。その主要な更新と改善は2030年までに終了し、2020年4月23日にリリースされる予定です。

中国には、Alibaba、NetEase、清華大学や中家大学などの教育ネットワークなど、多くのUbuntuミラーソースがあります。
例としてNetEase163ソースを取り上げて、Ubuntu20.04のデフォルトソースを変更する方法を確認します。

ステップ1：ソースファイルをバックアップします。

sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup

ステップ2：/etc/apt/sources.listファイルを編集します

ファイルの先頭に次のエントリを追加します（操作の前に対応するバックアップを作成してください）。

vi /etc/apt/sources.list
#vim /etc/apt/sources.list
