epel 提示有误

问题点参考：tuna/issues#687 (comment)

sed -e 's!^metalink=!#metalink=!g' \
    -e 's!^#baseurl=!baseurl=!g' \
    -e 's!//download\.fedoraproject\.org/pub!//mirror.nju.edu.cn!g' \
    -e 's!http://mirrors!https://mirrors!g' \
    -i /etc/yum.repos.d/epel.repo /etc/yum.repos.d/epel-testing.repo

简而言之，在新版本中的baseurl后的示例域名变为了download.example：

[epel]
name=Extra Packages for Enterprise Linux $releasever - $basearch
# It is much more secure to use the metalink, but if you wish to use a local mirror
# place its address here.
#baseurl=https://download.example/pub/epel/$releasever/Everything/$basearch/
metalink=https://mirrors.fedoraproject.org/metalink?repo=epel-$releasever&arch=$basearch&infra=$infra&content=$contentdir
enabled=1
gpgcheck=1
countme=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-$releasever
