While trying to upgrade my system to the latest hardware enablement stack from Ubuntu 12.04.2/Linux 3.5 I get the following error:



$ sudo apt-get install --install-recommends linux-generic-lts-raring xserver-xorg-lts-raring libgl1-mesa-glx-lts-raring

Reading package lists... Done

Building dependency tree

Some packages could not be installed. This may mean that you have

requested an impossible situation or if you are using the unstable

distribution that some required packages have not yet been created

or been moved out of Incoming.

The following information may help to resolve the situation:



The following packages have unmet dependencies:

 libgl1-mesa-glx-lts-raring : Depends: libglapi-mesa-lts-raring (= 9.1.4-0ubuntu0.1~precise1) but it is not going to be installed

                              Recommends: libgl1-mesa-dri-lts-raring (>= 7.2) but it is not going to be installed

 xserver-xorg-lts-raring : Depends: xserver-xorg-video-all-lts-raring but it is not going to be installed or

                                    xorg-driver-video

                           Depends: xserver-xorg-input-evdev-lts-raring but it is not going to be installed

                           Recommends: x11-xserver-utils-lts-raring

                           Conflicts: libglapi-mesa:i386 (>= 0~)

E: Unable to correct problems, you have held broken packages.


How can I troubleshoot this?

This appears to be a known issue. The bug report includes a workaround similar to the one proposed in Bao Bui's answer:




After some trial and error the apt-get command that eventually worked
for me is:



sudo apt-get install -V libglapi-mesa-lts-raring libgl1-mesa-glx-lts-raring xserver-xorg-lts-raring xserver-xorg-input-all-lts-raring xserver-xorg-video-all-lts-raring libgl1-mesa-dri-lts-raring x11-xserver-utils-lts-raring libglapi-mesa-lts-raring:i386 libgl1-mesa-dri-lts-raring:i386 libgl1-mesa-glx-lts-raring:i386


Make sure to carefully check the suggested changes before proceeding
to ensure that no essential packages are removed!




I can confirm that this solution worked for me.





On a related note: Just a small warning for anyone planning to upgrade using the HWE. This upgrade was far from smooth for me. Aside from all the dependency issues described in this Q&A, I had to manually install Raring packages to get my WLAN (broadcom) to work. Similar issues might arise if you have hardware that's running using proprietary drivers (installed via the "Additional Drivers" dialog).



So be wary when installing these hardware enablement stacks. It's a a feature that obviously still needs a lot of work.
