当我使用 Ubuntu 21.04 推出全新的 LXC CT 时，我无法安装software-properties-common所需的内容apt-add-repository。
在一个全新的实例上，我以 root 身份登录并运行apt update，apt upgrade然后apt install software-properties-common得到以下输出：
root@kubernetes:~# apt install software-properties-common
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done

知道为什么我无法在全新实例上安装它吗？看起来有点混乱。

对于遇到此问题的其他人来说，解决方案是编辑/etc/apt/sources.list以下内容仅有的项目（注释掉其他所有内容）：
deb http://archive.ubuntu.com/ubuntu/ hirsute-proposed main
然后再次运行apt update以apt upgrade修复 libglib2.0-0 包，然后恢复sources.list到之前的状态（但保留建议的行），并且在再次尝试安装时它将起作用software-properties-common。
为什么必须对库存安装执行此操作确实令人困惑，并且用户体验很糟糕。
