"Peer's Certificate issuer is not recognized" while adding docker repo


Running:

yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

Produces:

Could not fetch/save url https://download.docker.com/linux/centos/docker-ce.repo to file /etc/yum.repos.d/docker-ce.repo:
[Errno 14] curl#60 - "Peer's Certificate issuer is not recognized."

Solution

  • I encountered this and solved it with

    yum reinstall ca-certificates
