Question

我很早以前安装了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，并尝试安装mysql5.7，但出现此错误：

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

当我也使用sudo dpkg --configre -a时也会收到此错误。

我使用sudo apt install mysql-server安装软件包。我尝试在线遵循一些指南，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。

Answer 1

这已为我修复（MySQL 8.0-Ubuntu 20.04）

sudo apt-get purge mysql\* libmysql\*
sudo apt autoremove

但是软件包“ mysql-client-core-8.0”没有卸载，所以...

sudo apt --fix-broken install
sudo apt-get --reinstall install mysql-client-core-8.0
sudo apt-get purge mysql\* libmysql\*
sudo apt autoremove
sudo apt update
sudo apt install mysql-server

没有更多错误！

Answer 2

好，我是这样解决的：

我使用Software & Updates应用程序删除了mariadb源
并执行以下步骤（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

Answer 3

尝试一下：

sudo dpkg -P mysql-server mysql-server-5.1
sudo apt-get autoremove
sudo apt-get clean
dpkg -l | grep -i mysql
sudo rm -rvf /var/lib/mysql
sudo apt-get install mysql-server

步骤dpkg -l | grep -i mysql将向您显示所有已安装的mysql模块。在下一步之前，它应该为空。

Answer 4

如果端口 (3306) 正被另一个应用程序使用，也可能发生此错误。就我而言，我有一个运行 mysql 的 docker 容器，该容器使用 3306 端口。因此我的本地 mysql 安装配置失败。

$ sudo netstat -nltp | grep LISTEN | grep 3306
$ sudo netstat -nltp | grep LISTEN | grep 3306
tcp6       0      0 :::3306                 :::*                    LISTEN      1017033/docker-prox 

sudo apt purge --auto-remove mysql*
sudo rm -r /etc/mysql
sudo rm -r /var/lib/mysql*

sudo apt install mysql-client-8.0 mysql-server-8.0 --fix-broken -y

尚未配置mysql-server-5.7
