我们都使用了 apt-get update和 --fix-missing选项。我们得到了同样的错误。
然后我们使用 sudo apt-cache policy libmysqlclient-dev 列出了可用的版本。 :
我们有:

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。 :
我们有 :

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？
