帮助清理ubuntu 22.04中的快照

Question

你好，我正在清理我的ubuntu22.04系统，从20.04升级到18.04，从16.04…升级到18.04。只是为了尽可能多的清理，学习新的东西。

我的问题是，我面对这张简单的清单：

所以我有一些问题：

例如，据我所知，ubuntu 22.04.1附带了gnome 42和一些仍在gnome 41中的应用程序，所以我可以安全地删除gnome-3-26-1604和gnome-3-28-1804和gnome gnome-3-38-2004快照？还有我可以删除他们的回复版本吗？

核心呢？我有核心，core18，core20…我想这是snap的核心，所以我应该至少保存一个核心？最近的那个？

3-Snapd-桌面-集成是必要的…它的名字表明是的很重要，但是版本0.1意味着放弃软件或者不再使用…的东西也许整合在其他地方

提前感谢

您可以尝试删除您认为未使用的gnome-和core-快照。如果您错了，系统只会返回一个错误，告诉您使用的是哪些快照。

下面是两个尝试删除core-的示例：

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

• 有关这个快照是什么以及它做什么的细节，请参见https://github.com/snapcore/snapd-desktop-integration。
• 0.1版意味着它处于开发的早期阶段，而不是被放弃。
