![APT/DPKG 已损坏 - 无法删除 mysql-server-core-5.5](https://linux22.com/image/699324/APT%2FDPKG%20%E5%B7%B2%E6%8D%9F%E5%9D%8F%20-%20%E6%97%A0%E6%B3%95%E5%88%A0%E9%99%A4%20mysql-server-core-5.5.png)
我想完全删除服务器上与 mysql 相关的所有软件包。但我似乎无法完成这项任务。APT 似乎无法理解服务器上未安装 mysql-server。是否可以手动告诉 apt 软件包已被删除?

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).
我也尝试过“清除”

运行 apt-get -f install 不能解决任何问题

逐个删除软件包也不起作用,系统提示“对话框”要求我为 mysql-server 设置 root 密码。
apt-get 删除 mysql 服务器 apt-get 删除 mysql 客户端 apt-get 删除 mysql 服务器核心
我会尽力按照您的意愿更新这个问题,但我现在正为此而烦恼。我几乎要重新安装整个服务器了。
答案1
从显示的消息来看,由于依赖关系,apt-get 停止,这是正确的行为。否则依赖该包的模块将停止工作。
正确的方法是阅读有关依赖于它的模块的消息,然后按顺序逐个删除它们,直到全部删除。
从消息来看, mysql-server-core
mysql-server 需要。因此您必须按顺序进行删除。
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
最好的方法始终是用来dpkg -l | grep mysql
检查已安装的相关包。
请尝试应用所述答案在这个问题中如果以上所有方法均失败。尽管如此,一些问题还是由指向包含旧的/有缺陷的安装脚本的过时的 debian/ubuntu 存储库引起的,但这种情况很少见。
