Hello all, thank you for taking the time to read my post! Firstly, I am running CentOS 6 as a virtual machine. This Vm/Template came packaged from Nagios and is also behind a proxy in a security sensitive environment. With the research I have done thus far it seems like my YUM key has fallen out of sync with the EPEL Repository.

I have cleared the yum cache, cleared the repo cache as part of my own troubleshooting and have run out of ideas to proceed. I will produce the output of 'yum update' tomorrow when I am in the office. Rapidshare London Calling on this page.

- I have verified that the requests are making it through the proxy (this process stopped working two months ago). I would welcome suggestions as to how I might gather more logs/information!
