mysql-server-5.7尚未配置

Question

很久以前，我安装了Mysql5.7，然后卸载它并安装了MariaDB禁用设备(mysql)配置文件。

现在，我卸载了MariaDB，并尝试安装mysql5.7，得到了以下错误：

Reading package lists... Done

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

当我使用sudo dpkg --configre -a时，我也会得到这个错误。

我使用sudo apt install mysql-server安装这个包。我试着在线学习一些指南，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

好吧，我用这样的方法解决了：

使用sources

• executed应用程序删除mariadb

• 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

的步骤如下(ref https://askubuntu.com/a/934576)：

Answer 2

这为我修复了它(MySQL 8.0 -Ubuntu20.04)

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

但是软件包"mysql-client-core-8.0“不卸载，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

别再犯错误了！

Answer 3

试试这个：

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将显示所有已安装的mysql模块。在接下来的步骤之前，应该是空的。
