The following information may help to resolve the situation: The following packages have unmet dependencies: mysql-client : Depends: mysql-client-8.0 but it is not going to be installed E: Unable to correct problems, you have held broken packages.

This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming.

解决：

这个错误提示表明安装 `mysql-client` 时出现了依赖性问题。具体来说，它指出 `mysql-client` 需要安装 `mysql-client-8.0`，但系统无法安装 `mysql-client-8.0`。

要解决这个问题，你可以尝试以下几种方法之一：

1. 确保你的 apt 源正确配置，并尝试更新软件包列表和依赖项：
“`
sudo apt update
sudo apt upgrade
sudo apt –fix-broken install
“`

2. 尝试安装缺少的依赖包 `mysql-client-8.0`：
“`
sudo apt install mysql-client-8.0
“`

3. 如果上述方法都不起作用，你可以尝试使用其他 apt 源或向 `/etc/apt/sources.list` 添加 `[universe] [multiverse]` 源，然后重试安装。

请注意，在执行任何操作前最好备份重要数据，并谨慎操作，以免造成系统不稳定或数据丢失。
