Unable to install or update using yum

centos yum dependencies

Solution 1

It appears you have a Centos 6 machine but have configured the Epel repository for Centos 7. That is not going to work. Remove it and install the Centos 6 Epel Repository at:

wget http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

Make sure you uninstall anything you added from the Centos 7 Epel repository as well.

That should do it.

Solution 2

Run the following

yum remove epel-release

Then run yum update

That should fix your problem
