Cannot install docker in a RHEL server
Building on top of @user3495504’s answer, what we did to fix the problem was adding an entry on top of the file /etc/yum.repos.d/docker-ce.repo, with this content: [centos-extras] name=Centos extras – $basearch baseurl=http://mirror.centos.org/centos/7/extras/x86_64 enabled=1 gpgcheck=1 gpgkey=http://centos.org/keys/RPM-GPG-KEY-CentOS-7 Then the installation command: yum -y install slirp4netns fuse-overlayfs container-selinux was successful. [Edit] enabled gpgcheck
