-This article will teach you how to check for updates, check the changed packages, and read the changelogs with _rpm-ostree db_ and its subcommands.
+这篇文章将教你如何使用 _rpm-ostree db_ 及其子命令检查更新、检查更改的软件包和阅读更新日志。
 
-The commands will be demoed on a Fedora Silverblue installation and should work on any OS that uses _rpm-ostree_.

-### Introduction
+### 简介
 
-Let’s say you are interested in immutable systems. Using a base system that is read-only while you build your use cases on top of containers technology sounds very attractive and it persuades you to select a distro that uses _rpm-ostree_.
+假设你对不可更改的系统感兴趣。在基于容器技术构建用例时使用只读的基本系统听起来非常有吸引力，它会说服你选择使用 _rpm-ostree_ 的发行版。
 
-You now find yourself on [Fedora Silverblue][4] (or another similar distro) and you want to check for updates. But you hit a problem. While you can find the updated packages on Fedora Silverblue with GNOME Software, you can’t actually read their changelogs. You also can’t [use _dnf updateinfo_ to read them on the command line][5], since there’s no DNF on the host system.
+你现在发现自己在 [Fedora Silverblue][4]（或其他类似的发行版）上，你想检查更新。但你遇到了一个问题。虽然你可以通过 GNOME Software 找到 Fedora Silverblue 上的更新包，但你实际上无法阅读它们的更新日志。你也不能[使用 _dnf updateinfo_ 在命令行上读取它们][5]，因为主机系统上没有 DNF。
 
-So, what should you do? Well, _rpm-ostree_ has subcommands that can help in this situation.
+那么，你应该怎么做呢？嗯，_rpm-ostree_ 有一些子命令可以在这种情况下提供帮助。
