Description Syam 2008-05-31 03:38:20 UTC

Description of problem:
I did a yum update a couple of days ago, and my system is updated now. I 
noticed this problem today when compiling NVIDIA drivers.
I seem to have two kernels installed:
2.6.25.3-18.fc9.i686 (I'm running this one, the default in my grub)
2.6.25-14.fc9.i686

For compiling NVIDIA drivers, I did:
yum install kernel-headers
and it downloaded headers for 2.6.25-14 (confirmed from /usr/src/
kernels/2.6.25-14.fc9.i686).
Since the two kernel versions have different numbering schemes, I'm not able to 
identify the newer kernel.

Which one is the new kernel?

Comment 1 Syam 2008-05-31 03:53:30 UTC

I had changed mirrorlist for fedoa-updates repo for using presto. I thought 
this might be causing the issue. So I changed it back to the original, and did:
yum remove kernel-devel
yum clean
yum install kernel-devel

But it's still showing 2.6.25-14 as available.
As an additional info, the kernel-headers package I have is 2.6.25.3-18.fc9.

https://fedoraproject.org/wiki/Packaging/NamingGuidelines#Package_Version

Package n-v-r values are ordinal.  Versions and releases are separated by the
'-', and version 2.6.25.3 is larger than version 2.6.25, meaning that
kernel-2.6.25.3-18.fc9 is newer than 2.6.25-14

Comment 3 Syam 2008-05-31 13:35:08 UTC

Thanks. I figured the versioning scheme after a bit of googling. But the 
problem with kernel-devel still exists. Yum lists only kernel-devel 
2.6.25-14.fc9, though the running kernel is the newer 2.6.25.3-18.fc9.
How do I install kernel-devel 2.6.25.3-18?

Comment 4 Neil Horman 2008-06-02 11:09:29 UTC

you just wait a few minutes, clean your yum cache with a yum clean all, and try
again.  I imagine that the devel package just got pushed a  bit later than the
base package.  Its there now:
http://download.fedora.redhat.com/pub/fedora/linux/updates/9/i386/kernel-devel-2.6.25.3-18.fc9.i686.rpm
I don't know if you need i386 or not, but its there for all the arches.
