APT/DPKG坏了-无法删除mysql-服务器-核心-5.5

Question

我希望完全删除服务器上与mysql相关的任何包。但我似乎无法完成这一任务。APT似乎无法理解mysql-server没有安装在服务器上。是否可以手动告诉apt一个包被删除了？

╭─root@home /etc/apt
╰─➤  apt-get remove mysql-server-core-5.5

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
mysql-server-5.5 : Depends: mysql-client-5.5 (>= 5.5.54-0+deb8u1) but it is not going to be installed
                Depends: mysql-server-core-5.5 (>= 5.5.54-0+deb8u1) but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a  solution).

我也试过“清洗”

╭─root@home /etc/apt
╰─➤  apt-get purge mysql-server-core-5.5                                                                             100 ↵

运行apt -f安装不会解决任何问题。

dpkg: error processing package mysql-server-5.5 (--configure):

运行apt-get安装mysql-服务器-5.5-重新安装两者都不使用。

╭─root@home /etc/apt
╰─➤  apt-get install mysql-server-5.5 --reinstall                                                                    100 ↵

尝试用dpkg --清除--强制--mysql--社区服务器-- mysql-server-5.5 -server-core-5.5手动删除

╭─root@home /etc/apt
╰─➤  dpkg --purge --force-all mysql-community-server mysql-server-5.5 mysql-server-core-5.5                            1 ↵

一个接一个地删除包也不起作用，提示我使用“对话框”来设置mysql服务器的根密码。

删除mysql服务器获取删除mysql客户端apt获取删除mysql服务器核心

我会尽我最大的努力来更新这个问题，如你所愿，但我目前正在拔出我的头发。我几乎要重新安装整个服务器了。

根据所显示的消息，由于依赖项，apt-get停止，这是正确的行为.否则，模块依赖于包将停止工作。

正确的方法是读取关于依赖于它的模块的消息，然后依次删除它们，直到您耗尽所有模块。

从消息来看，mysql-server需要mysql-server-core。所以你必须按顺序做移除。

sudo apt-get purge mysql-server
sudo apt-get purge mysql-client
sudo apt-get purge mysql-common
# I think when you uninstall mysql-server, it will also remove the core

最好的方法是始终使用dpkg -l | grep mysql来检查已安装的相关包。

如果上述所有问题都失败了，请尝试申请答案声明的在这个问题上。尽管如此，一些问题是由于指向过时的debian/ubuntu存储库而引起的，其中包含旧的/修补程序安装脚本，但这是很少见的。
