mysql-server-5.7 尚未配置

Question

我很久以前安装了Mysql5.7，之后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 并且我正在尝试安装 mysql5.7 并且出现此错误：

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

我也使用时出现此错误sudo dpkg --configre -a。

我使用sudo apt install mysql-server. 我试着在网上遵循一些指南，我删除了/var/lib/dpkg/info/mysql-server-5.7.postinst清除的 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 mariadb 源
• 执行了以下步骤（参考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
