Ubuntuは端末のコマンドラインを介してAliソースを交換します（誤って古いバージョンのubuntuの問題を解決します）

1. Ubuntuシステムのコード名を確認する

$ lsb_release -a

結果を得る：

No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 17.10

Codename:       artful

Aliyuanがサポートしているかどうかを確認するには、http： //mirrors.aliyun.com/ubuntu/dists/にアクセスしてください。

sources.listを変更します

$ sudo vi /etc/apt/sources.list

sources.list元のコンテンツを削除して、Aliyuanで置き換えます

ここでの各行の巧妙さはシステムのコードネームに対応する必要があることに注意してください。したがって、異なるシステムバージョン間のsources.listファイルはユニバーサルにすることはできません。

         注17.10バージョンであること、がが見 http://mirrors.aliyun.com/ubuntu/dists/あり、それはまだ取っていません。

その理由は、17.10などの非メインストリームバージョンがサポートされなくなったことです。解決策は、リンクを確認することです。簡単に言えば、ドメイン名をold-releases.ubuntu.comに変更する必要があります
