Fedu doesn't update either:
sudo dnf update fedy

You might have experienced an issue with copr gpg key been expired if you have upgraded from a previous fedora version.

sudo rpm -e $(rpm -qa gpg-pub* |grep 2da862e5) might fix it
(
Now I'm not sure about why this is still an issue with dnf5 copr, I thought experired gpg keys should be gracefully handled ...)
