我snapd按照以下说明从我的电脑中删除了https://ubuntuforums.org/showthread.php?t=2328152：
sudo apt purge snapd ubuntu-core-launcher squashfs-tools
但是，我的系统仍然充满了与该包相关（我认为）的文件和目录snapd，正如您从结果中看到的那样locate snapd。
我有两个问题：
- 为什么不
apt purge删除所有这些文件？ 删除它们是否安全？或者系统或其他软件包是否正在使用它们？如果是，我该如何查找？

打包系统 (dpkg) 通常不会删除在打包系统之外创建的 dfile。您在此处引用的大多数文件都是在系统上安装 snap 时生成的。但是，看起来您仍然安装了该snapd软件包，以及libsnapd-glib1和snapd-login-service。
尝试sudo apt-get autoremove --purge libsnapd-glib1 snapd移除它们。
