无法安装mysql-server包

Question

我试图在debian上安装mysql-服务器包，但我得到了一个错误：

t@mintserver:~$ sudo apt install mysql-server
Reading package lists... Done

我读过许多其他的回复，这些回复告诉我要清除包，纠正依赖关系，但什么也不起作用。

请运行sudo dpkg --audit或sudo dpkg -C，这是一样的。它可能会给你建议该怎么做。

编辑:根据你的评论，

设置mysql-server-5.7 (5.7.29-0ubuntu0.18.04.1)更新-选项: error: alternative path /etc/mysql.cnf不存在dpkg:错误处理包mysql-server-5.7 (-配置)：安装mysql-server-5.7包安装后脚本子进程返回错误退出状态2错误在处理过程中遇到: mysql-server-5.7

更新-替代程序找不到这个mysql.cnf文件。

你能试着创建那个文件吗？请做：sudo nano /etc/mysql/mysql.cnf填充这个内容

[mysql]

然后，重试dpkg --configure <package>

或者，这可能会做好以下工作：

sudo apt-get remove --purge mysql-\*
sudo apt-get install mysql-server mysql-client
