Error: Failed to synchronize cache for repo 'fedora' from 'https://mirrors.fedoraproject.org/metalink?repo=fedora-$releasever&arch=x86_64': Cannot prepare internal mirrorlist: file "repomd.xml" was not found in metalink

Editing /etc/yum.repos.d/fedora*.repo, replacing all instances of "$releasever" with "22" fixes the problem

Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1. Fresh install of Fedora 22
2. Attempt to install packages
3.

Actual results:
Error: Failed to synchronize cache for repo 'fedora' from 'https://mirrors.fedoraproject.org/metalink?repo=fedora-$releasever&arch=x86_64': Cannot prepare internal mirrorlist: file "repomd.xml" was not found in metalink


Expected results:
$releasever should be understood by dnf as it worked in yum

Additional info:
I was able to install 1 package successfully, and it seems that perhaps a dependency update caused the problem. It worked immediately after the install.
