我有以下问题：我想再次安装MySQL（我删除了ibdata文件，所以我不得不再次安装它）。我必须使用 apt-get purge mysql-server mysql-common 删除MySQL。然后我用 apt-get install mysql-server 再次安装它。
安装开始很好，但后来我收到错误。一旦我在这个蓝色终端窗口输入了MySQL密码，我就收到错误。
这也是一个蓝色对话。这是错误：
Package configuration
┌─────────────────────┤ Configuring mysql-server-5.6 ├──────────────────────┐
│ │
│ Unable to set password for the MySQL "root" user │
│ │
│ An error occurred while setting the password for the MySQL │
│ administrative user. This may have happened because the account already │

│ server. │
│ │
│ You should check the account's password after the package installation. │

│ Please read the /usr/share/doc/mysql-server-5.6/README.Debian file for │
│ more information. │
│ │
│ <Ok> │
│ │
└───────────────────────────────────────────────────────────────────────────┘
但它不仅仅是错误。这两个错误。当MySQL服务器尝试启动时，此错误即将发生。 MySQL无法启动，我收到了这个错误：

有人能帮助我吗？我绝望:(
谢谢！
