dnf update fails

[Willis Yonker]

Hi,

I did a fresh install of Fedora 29 a few weeks ago.  It seems to work fine
except now dnf seems to not want to use the fedora repo.  If I remove the
fedora.repo file, or even disable the fedora repo in the file, it works.
Any help would be appreciated!

Thank you!

If I run dnf -v update, here is the last part of the output:

Fedora 29 - x86_64
