This question already has an answer here:

I have Ubuntu version 14.04.2 installed and want to upgrade to 14.04.3 (Kernel 3.19 has few fixes for me)

When I do

cat /etc/lsb-release

I get

DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=14.04
DISTRIB_CODENAME=trusty
DISTRIB_DESCRIPTION="Ubuntu 14.04.3 LTS"

But I still have 3.16 Kernel, I never got any message about upgrade and when I do

do-release-upgrade

(either with -d or -p) I get

Checking for a new Ubuntu release
No new release found

I tried to reboot, for the case that I missed the upgrade, but nothing

I also have set

Prompt=lts

in

/etc/update-manager/release-upgrades

How can I get the upgrade?

Thanks ^^

Yes. More info here: https://wiki.ubuntu.com/TrustyTahr/ReleaseNotes#LTS_Hardware_Enablement_Stack

Anyone wishing to opt into the hardware enablement stack for Trusty may do so by running following command which will install the linux-generic-lts-vivid and xserver-xorg-lts-vivid packages:

sudo apt-get install --install-recommends linux-generic-lts-vivid xserver-xorg-core-lts-vivid xserver-xorg-lts-vivid xserver-xorg-video-all-lts-vivid xserver-xorg-input-all-lts-vivid libwayland-egl1-mesa-lts-vivid 

If you are on an amd64 system that boots with UEFI, you will also need the matching signed kernel:

sudo apt-get install linux-signed-generic-lts-vivid 

For anyone interested, the specifics regarding the exact policies and procedures regarding the support, maintenance, and upgrade paths for the hardware enablement stack has been documented at the following location: https://wiki.ubuntu.com/Kernel/LTSEnablementStack

I did some extra googling and found out, that I really have 14.04.3 version already, but the kernel does not upgrade with it automatically. So I did

sudo apt-get install linux-generic-lts-vivid

To get the kernel
