N: This must be accepted explicitly before updates for this repository can be applied. See apt-secure(8) manpage for details.您在尝试安装软件时遇到的问题是因为Debian Buster版本的软件仓库已经从 “stable” 更改为 “oldoldstable”。这通常在Debian发布了新的稳定版之后发生，旧的稳定版会被移至”oldstable”状态，而再旧的版本则变成”oldoldstable”。
这里的错误信息表明APT软件包管理器要求您确认这个变化，然后才能继续更新和安装软件包。
要解决这个问题，您需要执行以下步骤：
apt-get update --allow-releaseinfo-change然后更新软件包：
apt-get update
apt-get install sudo如果有缺失的软件包，您可以添加 --fix-missing 选项：
sudo apt-get install sudo --fix-missing
