This question already has an answer here:

I'm trying to install the hardware enablement stack onto 12.04 but I'm running into the following dependency issue:

The following packages have unmet dependencies:

libgl1-mesa-glx-lts-trusty: Depends: libglapi-mesa-lts-trusty (= 10.1.3-0ubuntu0.1~precise1) but 10.1.3-0ubuntu0.1~precise1 is to be installed
                            Depends: libx11-6 (>= 2: but 2: is to be installed
                            Depends: libxdamage1 (>= 1:1.1) but 1:1.1.3-2build1 is to be installed
xserver-xorg-lts-trusty: Depends: xserver-xorg-core-lts-trusty (>= 2:1.11) but 2:1.15.1-0ubuntu2~precise1 is to be installed

How can I circumvent this and get the HWE to install?

This is weird. The dependencies are met, but apt is refusing to install the packages. If you have aptitude, can you try installing it through aptitude so that we can get more descriptive error messages? – saiarcot895 Jul 16 '14 at 11:43

I got the same error messages when I tried to update my 12.04 with kernel 3.5.0-48-generic. Since the dependency that was not being met was libglapi-mesa-lts-trusty I tried to install it manually and got this error:

libglapi-mesa-lts-trusty: Conflicts: libglapi-mesa Conflicts: libglapi-mesa

So I used synaptic to remove libglapi-mesa and then entered the following on a terminal window:

sudo apt-get install libgl1-mesa-glx-lts-trusty xserver-xorg-lts-trusty

And that successfully updated my system to kernel 3.13.0-30-generic. After rebooting got a message that said that my hardware enablement stack was now supported till 2017.

Hope this helps.
