Tried the second link but still same issue. Imported and installed key and repo fine but when I issue the command to install kernel, it says
Package kernel-2.6.32-642.6.1.el6.x86_64 already installed and latest version while uname shows kernel as
[root@voip ~]# uname -a
Linux voip 2.6.32-042stab092.3 #1 SMP Sun Jul 20 13:27:24 MSK 2014 x86_64 x86_64 x86_64 GNU/Linux
I want to update this kernel
2.6.32-042stab092.3....
I have downloaded required kernel headers and devel packages from
http://opennodecloud.com/CentOS/6/opennode/
but when I install them they give warning
warning: vzkernel-devel-2.6.32-042stab092.3.x86_64.rpm: Header V4 DSA/SHA1 Signature, key ID a7a1d4b6: NOKEY .. It looks like they are no longer compatible with CentOS 6 and I have to update kernel and its headers+devel packages.
strange thing is that both devel and headers are shown as installed but still not listed by yum.
