epel/x86_64/metalink | 2.0 kB 00:00:00
Could not parse metalink https://mirrors.fedoraproject.org/metalink?repo=epel-7&arch=x86_64&infra=$infra&content=$contentdir error was
File /var/cache/yum/x86_64/7Server/epel/metalink.xml.tmp is not XML
....
File /var/cache/yum/x86_64/7Server/epel/metalink.xml does not exist

ls -l /var/cache/yum/x86_64/7Server/epel/metalink.xml.tmp

ls: cannot access /var/cache/yum/x86_64/7Server/epel/metalink.xml.tmp: No such file or directory

So, it would appear that the installation should have created /var/cache/yum/x86_64/7Server/epel/metalink.xml.tmp but didn't. Any ideas why this happened and how to fix? Obviously, if I could just get a valid metalink.xml file I should be able to just copy into the correct location and move foreward. Any help is greatly appreciated.
