YUM INSTALL OR UPDATE  MAY FAIL     Nov 2019

Repos in directory /etc/yum.repos.d have mirror line set to "https:" and some mirrors may require "http:" .

Alternative to mirror is to uncomment baseurl lines and comment out mirror lines. 

For fedora*.repo , then add to the path "archive/" after "pub/"
