How do I install Fedora utilities on my Fedora 20 installation after getting errors?

http://ift.tt/1iZHv9S

I was trying to install Fedora utilities on my Fedora 20 installation, but it wasn’t installed and since then I just get this message for every command I enter :

Loaded plugins: fastestmirror, langpacks, refresh-packagekit

File contains no section headers.

file: file://///etc/yum.repos.d/fedorautils.repo, line: 1

‘rn’

I need help please!
