In our base CentOS 6.3 image it uses a few endpoints in the EPEL repos that are set by default that use SSL 3.0. Due to this you will receive the error noted below when attempting to use
yum update from the instance. This article will show you how to remedy that while we work on deploying an updated CentOS 6.x image.
Loaded plugins: fastestmirror, security Determining fastest mirrors Error: Cannot retrieve metalink for repository: epel. Please verify its path and try again.
We will update this knowledge base article once we have an updated and fixed CentOS 6.x image.
The CentOS 5.8 and CentOS 7 images available to use don’t have this issue.
Running this command will update the repo to use HTTP rather than HTTPS:
sudo sed -i "s/mirrorlist=https/mirrorlist=http/" /etc/yum.repos.d/epel.repo You should then be able to update with this command:
yum -y updateSource: https://community.hpcloud.com/article/centos-63-instance-giving-cannot-retrieve-metalink-repository-epel-error
