Error downloading packages:
原因
2024/6/30の時点でCentOS7のサポートが終了し非推奨になったため。
非推奨になり、ダウンロード先のURL上にファイルを置かなくなった(と考えられます。)
具体例 山形大学のurlの場合
コンソール画面で表示されたURLの一つを試しに調べてみます。
今回は最初に表示された山形大学のurlを調べてみます。
https://ftp.yz.yamagata-u.ac.jp/pub/linux/centos/7.9.2009/
readme ファイルのみが置かれています。
readmeの内容が以下のとおりです。

This directory (and version of CentOS) is deprecated.
