Hi

Uname -r gives
3.4.68-9.el6.centos.alt.x86_64
If I check the mirror the rpm I need is there.
If I wget the rpm and
execute rpm2cpio kernel-devel-3.4.68-9.el6.centos.alt.x86_64.rpm | cpio -idmv
I can see /usr/src/kernels/3.4.68-9.el6.centos.alt.x86_64/*

I've done yum clean all but when I do
If yum [re]install kernel-devel*
I get told
Package kernel-devel-2.6.32-358.23.2.el6.x86_64 already installed and latest Nothing to do

And in folder

/usr/src/kernels/
drwxr-xr-x. 22 root root 4096 Nov 22 23:25 2.6.32-358.23.2.el6.x86_64
drwxr-xr-x. 22 root root 4096 Nov 22 23:55 2.6.32-358.23.2.el6.x86_64.debug

In /lib/modules/3.4.68-9.el6.centos.alt.x86_64 is the link
build -> ../../../usr/src/kernels/3.4.68-9.el6.centos.alt.x86_64
(which is therefore invalid)

So, try again being more specific:
yum install kernel-devel-$(uname -r)
<snip>Setting up Install Process
No package kernel-devel-3.4.68-9.el6.centos.alt.x86_64 available.
Error: Nothing to do

Any clues?

Thanks in advance

Kevin

I'm not sure what your question is...RHEL/CentOS 6 uses the 2.6.32 kernel. Are you trying to force it to use a different kernel? For what purpose?

I'm not sure why uname -r is telling you you're running 3.4, because you shouldn't be, unless some time in the past you manually forced it to install and use a non-standard kernel, in which case yum won't be able to help you.

RHEL/CentOS won't be moving to the 3.x kernel until version 7. If you need bleeding-edge, then a slow release long term support "stable" distro like RHEL/CentOS is not for you.
