删除以前安装的 MariaDB 后尝试在 Ubuntu 17.10 上安装 MySQL。
为了清除所有内容，我运行了以下命令：
sudo apt-get remove --purge *mysql*
sudo rm -rf /etc/mysql /var/lib/mysql
sudo apt-get remove --purge *mariadb*
sudo apt-get autoremove
sudo apt-get autoclean
已验证 MySQL 和 MariaDB 均已被删除：
dpkg -l | grep mariadb
dpkg -l | grep mysql
现在当我尝试重新安装 MySQL
sudo apt update
sudo apt install mysql-server
输出：

我尝试注释掉 /var/lib/dpkg/info/mysql-server-5.7.postinst 中的第 143 行，但没有帮助。
任何帮助都将不胜感激。考虑使用 docker 镜像作为解决方法。

因此我能够使用以下命令成功安装最新版本的 MySQL。
再次，让我们清除所有东西
sudo apt-get remove --purge *mysql*
sudo rm -rf /etc/mysql /var/lib/mysql
sudo apt-get remove --purge *mariadb*
sudo apt-get autoremove
sudo apt-get autoclean
再次确认 MySQL 和 MariaDB 均已删除
dpkg -l | grep mariadb
dpkg -l | grep mysql
按照此答案中概述的步骤修复任何 dpkg 锁问题：

cd /tmp/ && wget https://dev.mysql.com/get/mysql-apt-config_0.8.10-1_all.deb
sudo dpkg -i mysql-apt-config_0.8.3-1_all.deb
sudo apt-get update
sudo apt-get install mysql-server mysql-client
