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.
The commands will be demoed on a Fedora Silverblue installation and should work on any OS that uses rpm-ostree.

You now find yourself on Fedora Silverblue 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 can8217t actually read their changelogs. You also can8217t use dnf updateinfo to read them on the command line since there8217s no DNF on the host system.
