Most EPEL mirrors dropped EL6 packages after the product retirement of RHEL 6 on 30 November 2020.
There are currently
11 active mirrors left that still provide access to EPEL 6. You have to edit
/etc/yum.repos.d/epel.repo manually and either provide the standard
metalink URL
Code:
metalink=https://mirrors.fedoraproject.org/metalink/?repo=epel-6&arch=$basearch
or select one or several mirrors from the link above for
baseurl.
In the latter case the URL(s) should point to
Fedora archive instead of the usual EPEL path, e.g.
Code:
baseurl=http://dl.fedoraproject.org/pub/archive/epel/...
