Hi Vedsar,<br>
<br>
Try disabling IPv6 if not using it, it appears that you're trying to<br>
acess the repo by its IPv6 address.<br>

<br>
</span><a href="http://mirrorlist.centos.org" target="_blank">mirrorlist.centos.org</a> has an IPv6 address so should work:<br>

I have seen package installs fail sometimes too so I now use a local mirror. Try running packstack again or failing that you can also install those packages manually and then rerun packstack (with the same answer file).<br>
