运行“apt-get remove dependencies-names”后，“dpkg -l”中仍然存在依赖项

Question

我怀疑安装xfce4会导致 Ubuntu 中出现一些问题，因此我使用apt-get remove xfce4 xfce4-goodeis.

但是当我运行 'dpkg -l' 时，我仍然可以看到xfce4 的一些库和包：

$ dpkg -l | grep -i xfce

我复制粘贴了所有这些包\库以形成一个apt-get remove删除所有这些依赖项的命令，并且该命令正常运行，但运行dpkg -l | grep -i xfce再次显示这些依赖项！

为什么这些依赖项仍然安装？

Answer 1

请注意rc列表开头的 。

r：删除（标记为删除）
c：存在配置文件。

apt-get remove和purge(From man apt-get)之间的区别

   remove
       remove is identical to install except that packages are removed instead of installed.
       Note the removing a package leaves its configuration files in system.

   purge
       purge is identical to remove except that packages are removed and purged (any
       configuration files are deleted too).

当你选择时apt-get remove，你dpkg -l反映了这一点。如果你会被利用，apt-get purge你可以避免这种情况。要摆脱这些，请在终端中尝试，

dpkg --list | grep "^rc" | cut -d " " -f 3 | xargs sudo dpkg --purge

它将清除所有标记为要删除的包。在清除它们之前，您可以检查要清除的列表，

dpkg --list | grep "^rc" | cut -d " " -f 3 

我想除了那些来自xfce. 如果您不确定。使用以下代替，

dpkg --list | grep -i xfce | cut -d " " -f 3 | xargs sudo dpkg --purge
