On 14.04, my kernel version is 3.11.0-18?

After upgrading to 14.04, my kernel is not upgraded! it's like before:

Linux Boxi 3.11.0-18-generic #32-Ubuntu SMP Tue Feb 18 21:11:14 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

Here's what I did:

sudo apt-get update
sudo apt-get dist-upgrade
sudo do-release-upgrade
sudo apt-get update
sudo apt-get dist-upgrade

lsb_release -a
