Unable to install packages rpms and it tries multiple mirrors and fails eventually. This issue is happening from yesterday, it was working fine earlier, not sure what changed in repomd.xml file. Is anyone else facing the same issue?

@mokugo-devops this error occurs even while spinning up new instances via terraform. And I tried clean and did a update, same error. — Sanjay M. P., Jun 13 '20 at 12:22

This appears to be a wider known issue related to the timestamp property inside of the repomd.xml file differing from the revision property.

The current suggestion is the following:

Open the /etc/yum.repos.d/epel.repo file.
Comment out the metalink property.
Uncomment the baseurl property.

After doing this either run yum clean metadata or yum clean all.

This should only be done for the short term, with this reverted once the issue has been fixed.

Looks like there's an issue in the CentOS package repository.

As a workaround, you can download the epel-release package manually and install it using the following commands;

wget https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
sudo yum install epel-release-latest-7.noarch.rpm
