Ubuntu – Ubuntu 14.04 upgrading Hardware Enablement Stack (HWE) shows unmet dependencies

14.04hardware-enablement-stackpackage-management

When upgrading from to the new Hardware Enablement Stack manually using this command:

sudo apt-get install --install-recommends linux-generic-lts-utopic xserver-xorg-lts-utopic libgl1-mesa-glx-lts-utopic libegl1-mesa-drivers-lts-utopic

This error comes up:

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:

E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.

What could be the cause and how can I solve this?

Best Answer

I had the exact same problem, and this worked for me:

  1. I installed the 14.04 (trusty) versions of those same packages first:

    sudo apt-get install --install-recommends linux-generic-lts-trusty xserver-xorg-lts-trusty libgl1-mesa-glx-lts-trusty libegl1-mesa-drivers-lts-trusty

  2. Once I installed those, I was able to run the command to upgrade the enablement stack:

    sudo apt-get install --install-recommends linux-generic-lts-utopic xserver-xorg-lts-utopic libgl1-mesa-glx-lts-utopic libegl1-mesa-drivers-lts-utopic

  3. Lastly, a bit of cleanup:

    sudo apt-get autoremove

Edit:

After following the above steps, Steam tried to install a couple packages (libgl1-mesa-dri:i386 and libgl1-mesa-glx:i386) and they were failing. I was able to fix it easily:

sudo apt-get install libgl1-mesa-dri-lts-utopic:i386 libgl1-mesa-glx-lts-utopic:i386

I'll have to remember that pattern for packages in the future if they fail installing/upgrading (try adding -lts-utopic to the package name).
