The remote host is missing an update to linux-source-2.6.15 announced via advisory USN-752-1. ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. If you use linux-restricted-modules, you have to update that package as well to get modules which work with the new kernel version. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-server, linux-powerpc), a standard system upgrade will automatically perform this as well. For details on the issues addressed in this update, please visit the referenced security advisories.

The problem can be corrected by upgrading your system to the following package versions: Ubuntu 6.06 LTS: linux-image-2.6.15-54-386 2.6.15-54.76 linux-image-2.6.15-54-686 2.6.15-54.76 linux-image-2.6.15-54-amd64-generic 2.6.15-54.76 linux-image-2.6.15-54-amd64-k8 2.6.15-54.76 linux-image-2.6.15-54-amd64-server 2.6.15-54.76 linux-image-2.6.15-54-amd64-xeon 2.6.15-54.76 linux-image-2.6.15-54-hppa32 2.6.15-54.76 linux-image-2.6.15-54-hppa32-smp 2.6.15-54.76 linux-image-2.6.15-54-hppa64 2.6.15-54.76 linux-image-2.6.15-54-hppa64-smp 2.6.15-54.76 linux-image-2.6.15-54-itanium 2.6.15-54.76 linux-image-2.6.15-54-itanium-smp 2.6.15-54.76 linux-image-2.6.15-54-k7 2.6.15-54.76 linux-image-2.6.15-54-mckinley 2.6.15-54.76 linux-image-2.6.15-54-mckinley-smp 2.6.15-54.76 linux-image-2.6.15-54-powerpc 2.6.15-54.76 linux-image-2.6.15-54-powerpc-smp 2.6.15-54.76 linux-image-2.6.15-54-powerpc64-smp 2.6.15-54.76 linux-image-2.6.15-54-server 2.6.15-54.76 linux-image-2.6.15-54-server-bigiron 2.6.15-54.76 linux-image-2.6.15-54-sparc64 2.6.15-54.76 linux-image-2.6.15-54-sparc64-smp 2.6.15-54.76 After a standard system upgrade you need to reboot your computer to effect the necessary changes. https://secure1.securityspace.com/smysecure/catid.html?in=USN-752-1
