Hello Linux Geeksters. As you may know, the Linux Kernel 3.10 Stable has been officially released yesterday. And Canonical has already updated Ubuntu 13.10 Saucy Salamander (which is still under development) to it.
Canonical hopes to release Ubuntu 13.10 Saucy Salamander with the Linux Kernel 3.11 stable, but nobody can know for sure if Kernel 3.11 will be stable in October, when Ubuntu Saucy is scheduled.
If you are using a daily build of Ubuntu 13.10 Saucy Salamander and want to upgrade to the latest stable kernel available (kernel 3.10 for now), you can either upgrade the entire system (including the kernel):
$ sudo apt-get update
$ sudo apt-get dist-upgrade
Or, just install the Linux Kernel 3.10 , by following the instructions from this article.
