Thanks for the responses. Sorry for the delay, July 4 is the Independence Day holiday here in the US, and I have been visiting with family the past couple of days.

It's not wildcarding on cups*, so that's not it. The repo database just appears to be massively hosed somehow:

[root@cobweb yum.repos.d]# dnf repoquery --whatprovides /usr/bin/foomatic-rip

What does "dnf repoquery --whatprovides /usr/bin/foomatic-rip" tell you?

I also get "no matching packages" responses to "dnf list" on packages
that are already installed:

root@cobweb yum.repos.d]# dnf clean all
72 files removed
[root@cobweb yum.repos.d]# dnf list cups*
[...]
Error: No matching Packages to list

Do you have a file that starts with "cups" in your repos directory?
As someone else mentioned, escape the *.

[root@cobweb yum.repos.d]# rpm -qa | grep cups
cups-filesystem-2.1.0-2.fc23.noarch
python3-cups-1.9.72-8.fc24.x86_64
cups-libs-2.1.0-2.fc23.x86_64
cups-client-2.1.0-2.fc23.x86_64
cups-libs-2.1.0-2.fc23.i686
python2-cups-1.9.72-8.fc24.x86_64
cups-filters-libs-1.6.0-1.fc23.x86_64
cups-pk-helper-0.2.5-6.fc23.x86_64
[root@cobweb yum.repos.d]#

That shows you are missing the necessary package.  Try installing the "cups-filters" package.
