Snapd 不挂载 snap 块设备

发行版：Ubuntu 21.04 (Hirsute Hippo)

我多次删除了 snapd（显然删除了 snapd），然后在安装 snapd 后，所有 snap 都正常了。这次我重新安装了 AppArmor 并安装了 snapd，启用并运行，但这次没有安装 snap。

The following packages will be REMOVED:
  apparmor* apparmor-easyprof* apparmor-notify* apparmor-profiles* apparmor-profiles-extra* apparmor-utils* snapd*

我仍然有 /home/user/snap，但 /var/lib/snapd/snaps 是空的。这是恢复快照的方法吗？还是只是丢失了？/home/user/snap 是干什么用的？我假设再次安装丢失的快照将保留 /home/user/snap 的配置。我真的对此感到困惑，有人能解释一下吗？谢谢！

答案1

删除snapd还会删除所有已安装的 snap 和系统目录中安装的所有文件（至少，目前是这样）。因此，在重新安装 snap 后，您需要重新安装所有 snap。

用户配置数据永远不会被自动删除。您主目录中“snap”目录中的所有用户配置数据都将保留 - 如果您再次安装，则相应的 snap 可以使用这些数据。
