It is so weird, I have a centos7 VM box. Try to install dnf
because it is a dependency of another package.
Most instructions on internet is like this:
sudo yum install epel-release
sudo yum install dnf
But nothing installs. No package dnf available
Even followed DNF blog: http://dnf.baseurl.org/2016/07/01/fresh-dnf-for-rhel-7-and-centos-7/
# cat <<EOF > /etc/yum.repos.d/dnf-stack-el7.repo
[dnf-stack-el7]
name=Copr repo for dnf-stack-el7 owned by @rpm-software-management
baseurl=https://copr-be.cloud.fedoraproject.org/results/@rpm-software-management/dnf-stack-el7/epel-7-\$basearch/
skip_if_unavailable=True
gpgcheck=1
gpgkey=https://copr-be.cloud.fedoraproject.org/results/@rpm-software-management/dnf-stack-el7/pubkey.gpg
enabled=1
enabled_metadata=1
Still nothing installs
# cat /etc/centos-release
CentOS Linux release 7.4.1708 (Core)
# yum search dnf

WARNING: EPEL 7 DNF is very old and has issues to include security flaws. This appears to be the reason it was removed. That said here is the work around to get it working on Centos 7.
