So you can issue the following command:
# cp /etc/yum.repos.d/fedora-rawhide.repo.rpmnew /etc/yum.repos.d/fedora-rawhide.repoAnd you may be back to normal.
I say you "may" be back to normal, because, in my case, there is still an issue. I am behind a "transparent" proxy and the folks who update the fedora-rawhide.repo file love to use https. Well, this causes me to get the following error: "Cannot retrieve metalink for repository: rawhide. Please verify its path and try again". If you simply edit the fedora-rawhide.repo file and change the https to http, updates work fine.
It appears that there is some software downstream from the fedora-rawhide.repo parsing that has problems conducting https through our "transparent" proxy ... imagine that.
