即使在使用apt-get clean进行清理后，它也会显示有损坏的包装。1中提到的sudo dpkg -l | grep ^..r不返回任何内容。

TL;DR:必须降级libc6，然后才能安装build-essential
经历了同样的事情：
$ sudo apt install build-essential

查看了apt-cache policy g++，我认为这已经很满足了，所以我继续前进：
$ apt-cache policy g++

...重点是我收到的警告：dpkg: warning: downgrading libc6:amd64 from 2.31-0ubuntu9.3 to 2.31-0ubuntu9.2
现在我可以安装build-essential了。

Do you want to continue? [Y/n]我读了很多不同的stackoverflow帖子，这些帖子让我开始使用我不熟悉的apt-cache policy $package。然后我就随便玩玩。

在寻找了答案之后，我决定手动安装“正确”的版本，并在下载pkg文件时遇到了这个问题：
将以下行添加到/etc/apt/Soures.list：
deb http://archive.ubuntu.com/ubuntu/ focal-proposed main更新包索引：
sudo apt-get update添加此存储库后，我可以使用以下命令安装build-essential：

我想我偶然发现了一个非常简单的解决方案。没有降级或内核构建。刚跑完
sudo apt update && sudo apt upgrade -y在我的案例中，有3个存储库返回错误。比如,
E: The repository 'cdrom://Ubuntu 20.04 LTS _Focal Fossa_ - Release amd64 (20200423) focal Release' does not have a Release file.刚刚启动了软件更新程序，删除了有错误的PPA，现在我可以安装新软件而不需要
Depends: libc6 (>= 2.33) but 2.31-0ubuntu9.2 is to be installed错误。
