解决Ubuntu 16.04 EC2实例安装MySQL的依赖错误问题

问题重现

执行安装命令：

sudo apt-get install mysql-server

出现以下错误：

Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
linux-headers-5.13.0-1028-aws : Depends: linux-aws-5.13-headers-5.13.0-1028 but it is not going to be installed
mysql-server : Depends: mysql-server-8.0 but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

解决步骤

先执行系统提示的依赖修复命令，这是最直接的尝试：
```
sudo apt --fix-broken install
```
该命令会自动下载并安装缺失的依赖包，修复系统的依赖状态。
修复完成后，再次尝试安装MySQL：
```
sudo apt-get install mysql-server
```

如果修复命令失败，先更新系统源并升级现有包（注意Ubuntu 16.04已停止官方支持，源可能需要调整）：

sudo apt update && sudo apt upgrade -y

若更新时出现源无法访问的错误，需要替换为旧版本维护源：

备份原有源文件：

sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak

编辑源文件：
```
sudo nano /etc/apt/sources.list
```

将文件内所有内容替换为：

deb http://old-releases.ubuntu.com/ubuntu/ xenial main restricted universe multiverse
deb http://old-releases.ubuntu.com/ubuntu/ xenial-updates main restricted universe multiverse
deb http://old-releases.ubuntu.com/ubuntu/ xenial-backports main restricted universe multiverse
deb http://old-releases.ubuntu.com/ubuntu/ xenial-security main restricted universe multiverse

保存退出后，重新执行更新和修复命令：
```
sudo apt update && sudo apt --fix-broken install
```

若仍有问题，手动安装缺失的依赖包：
先安装缺失的内核头文件包：
```
sudo apt-get install linux-aws-5.13-headers-5.13.0-1028
```
再安装MySQL Server 8.0：
```
sudo apt-get install mysql-server-8.0
```
最后安装mysql-server元包：
```
sudo apt-get install mysql-server
```
