Can't dnf update any app

[armageddon]

When i use the command 'dnf update',always have error in 'Running transaction check
' What can i do to solve the problem?
------------------------------------------------------------------------------------------------------------
#dnf update
...etc
Running transaction check
Error: transaction check vs depsolve:
(annobin if gcc) is needed by redhat-rpm-config-116-1.el8.0.1.noarch
rpmlib(RichDependencies) <= 4.12.0-1 is needed by redhat-rpm-config-116-1.el8.0.1.noarch
To diagnose the problem, try running: 'rpm -Va --nofiles --nodigest'.
You probably have corrupted RPMDB, running 'rpm --rebuilddb' might fix the issue.
The downloaded packages were saved in cache until the next successful transaction.
You can remove cached packages by executing 'dnf clean packages'.

What output do you get from rpm -qa ? Is it a long list of hundreds of things? Or a short list a just a few?

What does rpm -a annobin rpm say?
