Ubuntu 13.10 Saucy Salamander is still under development for now, and will be released in October, probably with kernel 3.11.
The kernel of the Ubuntu Saucy version available for now, has been upgraded the kernel to kernel 3.10 RC5.
This is what a Canonical developer said, at the Ubuntu Kernel Team meeting in Salisbury:
“Our Saucy unstable branch has been rebased to the latest v3.10-rc5 upstream kernel. We are still holding off on a v3.10 based upload due to missing AUFS support as well as some DKMS package failures we would like to resolve. We have however gone ahead and rebased our Saucy master branch to the recent v3.9.5 upstream stable,”
To upgrade your Ubuntu 13.04 Raring Ringtail to Ubuntu 13.10 Saucy Salamander, do this:
$ sudo update-manager -d
Because of the -d parameter, the command will automatically search for the newest development release of Ubuntu available and install it.
You can also download the Ubuntu 13.10 Saucy Salamander daily build, burn it on a bootable USB stick and install it on your computer.
