Doesn’t seem to be a Docker Linux area so putting this here.
When I try and issue: sudo yum-config-manager
–add-repo
https://download.docker.com/linux/centos/docker-ce.repo
I get this message: 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 has an invalid signature.”
Anyone else not able to add the docker repository?
I did but it was specific to my RHEL 7 setup I think. I’ll tell you what it is in case it helps you.
I needed to add a reference to my SSL certificate in the yum config. Steps I took where:
sudo vi /etc/yum.conf
At the bottom of the file I added:
sslcacert=/etc/pki/ca-trust/some/location/to/cert/cert.pem
Check that your date on your machine is correct. I had this problem when one of my servers was showing a time of August 12, 2010! By fixing the time, the SSL stuff worked fine.
I am facing the same issue on centos 7 machine. I tried all the above mentioned solutions in vain. Is there a verified solution for this?
