You can safely uninstall 'fedora-repos-anaconda'. It's not actually
going to be any use for installed systems, it exists solely for anaconda
purposes. I think installed systems may be getting it because of an
error we made in TC7; did you install from TC7? I think from RC1 on it
shouldn't be included in the installed system.

The repos obviously ought to work (they need to work for OOTB network
installation) and that's currently being worked on, but you don't need
them on an installed system, so it's fine to remove them to avoid this
problem.
