GPG errors from dnf on linux9

Question

Recently installed Rocky Linux9 on a bunch of machines. No real problems except for some packages don't want to install.

Example: confluent-kafka-2.11. If I run dnf install confluent-kafka-2.11 -vv I get the usual downloading info but it ends with

Using rpmkeys executable at /usr/bin/rpmkeys to verify signatures
Problem opening package confluent-kafka-2.11-2.0.1cp8-1.noarch.rpm
The downloaded packages were saved in cache until the next successful transaction.
You can remove cached packages by executing 'yum clean packages'.
Error: GPG check FAILED

I've tried adding --nogpgcheck but it still doesn't work. What am I doing wrong?

Same problem with elasticsearch except I was able to manually install the gpg key. This won't work as soon as the package updates though.

There are multiple solutions here.

To actually solve the gpg issue, the question is, how did you add the repo and the gpg key?

What is the output of

sudo dnf list all | grep confluent
# and
sudo dnf repolist
