Why does `dnf updateinfo` just output the "Last metadata expiration check"

I am writing a program to control dnf, and it needs a list of available updates for further processing.

The command dnf updateinfo seems what I want, I tried it on CentOS 8 Stream, but it just outputs this:

Last metadata expiration check: 0:24:03 ago on Tue 09 Feb 2021 07:51:05 PM CST.

am I missing anything?

By the way, I want to know if there is a better way to do it with dnf?

Can't test this at the moment, but you migh want something like dnf check-update?

@BulletBob Thanks a lot, dnf check-update could be used to check if updates available and output the list of updates. I still want to try with dnf updateinfo，because it supports more arguments to get a different type of update.
