Cannot install 'xserver-xorg-lts-trusty'

[Giovanni Santini]

As reported by 'hwe-support-status' I should:
sudo apt-get install linux-generic-lts-trusty libgl1-mesa-glx-lts-trusty xserver-xorg-lts-trusty linux-image-generic-lts-trusty

1) lsb_release -rd
Description: Ubuntu 12.04.4 LTS
Release: 12.04
2) apt-cache policy xserver-xorg-core-lts-trusty
xserver-xorg-core-lts-trusty:
Installed: (none)
Candidate: 2:1.15.1-0ubuntu2~precise1
Version table:
 2:1.15.1-0ubuntu2~precise1 0

3) As reported by 'hwe-support-status' I should:
sudo apt-get install linux-generic-lts-trusty libgl1-mesa-glx-lts-trusty xserver-xorg-lts-trusty linux-image-generic-lts-trusty
I expected to see bunch of X stuff removed and another bunch installed.
4) Doing it gave me this text error:

So, I decided to try removing xserver-xorg-core, but...:
---
Package xserver-xorg-core is not installed, so not removed
---

I suppose this happens as I should remove all the lts-saucy packages... But I really don't want to destroy my Ubuntu, so I'm waiting for suggestions and filing this bug.
Also, as it is a dependencies problem, is not source-related nor binary-related so I didn't track down anything else.
If you need something, just tell me. Regards.
