大家好，这些天我正在清理我的 ubuntu 22.04 系统，它是从 20.04 升级而来的，而 20.04 是从 18.04 升级而来的，而 18.04 是从 16.04 升级而来的...只是为了尽可能地清理，并学习新的东西。
我的问题是我面临这个快照列表：

所以我遇到了一些问题：
1 - 例如，据我所知，ubuntu 22.04.1 附带 gnome 42，而一些应用程序仍在 gnome 41 中，因此我可以安全地删除 gnome-3-26-1604、gnome-3-28-1804 和 gnome gnome-3-38-2004 snap 包吗？我也可以删除它们各自的版本吗？
2 - 那么核心呢？我有 core、core18、core20……我猜这是 snap 的核心，所以我应该保存至少一个核心？最新的那个？
3 - Snapd-desktop-integration 是必要的……它的名字表明它很重要，但 0.1 版本表明它是废弃软件或不再使用的东西……也许集成在其他地方
提前致谢
答案1
您可以尝试删除您认为未使用的快照。如果您错了，系统只会返回一个错误，告诉您哪些快照正在使用它gnome-。core-
以下是尝试删除的两个示例core-：
me@me:~$ sudo snap remove core18
core18 removed
me@me:~$ sudo snap remove core20
error: cannot remove "core20": snap "core20" is not removable: snap is being used by snaps discord,
firefox, gnome-3-38-2004, snap-store, snapd-desktop-integration and 1 more.
不要删除snapd-desktop-integration
- 看https://github.com/snapcore/snapd-desktop-integration了解此 snap 是什么以及它能做什么的详细信息。
- 0.1 版本意味着处于开发的早期阶段，并不意味着已被放弃。
