mysql-server-5.7 尚未配置

Question

我很久以前安装了 Mysql5.7，后来我卸载了它并安装了 MariaDB 禁用 apparmor (mysql) 配置文件。

现在我卸载了 MariaDB 并尝试安装 mysql5.7，但出现了这个错误:

 mysql-server
E: Sub-process /usr/bin/dpkg returned an error code (1)

当我也使用 sudo dpkg --configre -a 时出现此错误。

我使用 sudo apt install mysql-server 安装包。 我试着按照一些在线指南，我删除了 /var/lib/dpkg/info/mysql-server-5.7.postinst 清除了 mariadb、mysql 并尝试了很多东西。

好的，我是这样解决的:

• 我使用 Software & Updates 应用程序删除了 mariadb 源
• 执行了以下步骤(引用 https://askubuntu.com/a/934576):
• sudo apt purge mysql-client-5.7 mysql-client-core-5.7 mysql-common mysql-server-5.7 mysql-server-core-5.7 mysql-server
• sudo apt update && sudo apt dist-upgrade && sudo apt autoremove && sudo apt -f install
• sudo apt install mysql-server
