我们正在尝试安装 libmysqlclient-dev 并使用了这个命令：

我们同时使用了 apt-get update 和 --fix-missing 选项。我们遇到了同样的错误。

然后我们使用 sudo apt-cache policy libmysqlclient-dev:

列出了可用的版本

我们得到了：

libmysqlclient-dev:
  Installed: (none)
  Candidate: 8.0.28-0ubuntu0.20.04.3
  Version table:
     8.0.28-0ubuntu0.20.04.3 500

     8.0.19-0ubuntu5 500
        500 http://archive.ubuntu.com/ubuntu focal/main amd64 Packages

我们去了http://security.ubuntu.com/ubuntu/pool/main/m/mysql-8.0/：

我们使用 lsb_release -a 获得了 linux 的版本：

Distributor ID: Ubuntu
Description:    Ubuntu 20.04.4 LTS
Release:        20.04
Codename:       focal

然后我们尝试使用 sudo apt-get install libmysqlclient-dev=8.0.28-0ubuntu0.20.04.4 -y:

强制安装可用版本

我们得到了：

Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Version '8.0.28-0ubuntu0.20.04.4' for 'libmysqlclient-dev' was not found

我们如何安装这个包？
