![mysql-common无法卸载](https://linux22.com/image/881276/mysql-common%E6%97%A0%E6%B3%95%E5%8D%B8%E8%BD%BD.png)
我正在尝试完全卸载 mysql 以便稍后重新安装它,在卸载所有与 mysql 相关的软件包后,mysql-common 似乎仍然处于损坏状态。
$ sudo dpkg -l | grep mysql
pc mysql-common 5.6.28-0ubuntu0.15.10.1 all MySQL database common files, e.g. /etc/mysql/my.cnf
但运行 apt-get remove
$ sudo apt-get remove mysql-common

此外,我删除了所有与 mysql 相关的目录和文件。
我怎样才能摆脱这个挥之不去的破损包裹?

如果某些依赖项消失,或者由于某种原因删除了某些配置文件,则某些软件包无法卸载。最终您将得到一个未完全安装或未完全卸载的软件包。
在这种情况下,解决方案是卸载sudo apt-get install
软件包。如有必要,请执行sudo apt-get install --reinstall [package]
。缺失的文件将添加到系统中,并即时安装任何缺失的依赖项。然后可以按照通常的方式完全卸载软件包:sudo apt-get remove [package]
。
如果apt-get
因为其他(依赖性)问题而拒绝重新安装该包,则只能使用apt-get
下载该包并dpkg
直接使用来安装它:
apt-get download mysql-common
sudo dpkg -i mysql-common_*.deb
sudo apt-get install -f
有时你可以跳过下载,因为 Apt 倾向于保留以前下载和安装的软件包的存档,/var/cache/apt/archives/
因此你可以直接从第 2 步开始:
sudo dpkg -i /var/cache/apt/archives/mysql-common_*.deb
