But check that you can actually get onto the internet. ping some hostname and if those don't work, then do further troubleshooting. Error 14 seems to be connectivity issues. Since you said it worked before, check DNS setting etc. as per the linked posts.

Google has tons of hits on this issue.

As ericson007 said

Most probably its a net connectivity issue so make sure you are connected to internet and your IP is not under some sort of firewall. It can also happen with restriction on your IP.

you can give a check with google DNS

Thanx for the reply guys. The internet connection at my system is working very well. Internet is working fine. Few days back I was trying to connect my centos system with windows system using Telnet / VLC. So could I have unknowingly disturbed some port. But I can SSH the system using IP address by putty.

is it VLC or VNC?

So is it working now? I do not see what being able to putty into a machine on the LAN has to do with not being able to download from a repo on the net. I doubt there would be port disturbance as ssh is on 22 and VNC in the 5900 range. I doubt this is the cause. I bet it would probably have something to do with resolving hostnames over the net.

Yup, it's working now, but how the hell gpgcheck was enabled. Anyways, it was VLC and not VNC. Thanx bro.

It was not the gpg key which was the problem, it was the mirror link i.e base url
So if you think your problem is resolved kindly mark the thread as "solved"

All those errors start with
which means you still had/have the repo enabled that points to your local CD/DVD drive mount point.
Disable that unless you have no internet cxn.
