In Ubuntu 14.04, when I try to install steam via .deb file, it shows:

Steam needs to install these additional packages: libgl1-mesa-dri:i386, libgl1-mesa-glx:i386, libc6:i386

Then it asks for my password. I input my password, the terminal loads, and then says this:

Reading package lists... Done

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:i386 : Depends: libglapi-mesa:i386 (= 10.1.3-0ubuntu0.5)
 unity-control-center : Depends: libcheese-gtk23 (>= 3.4.0) but it is not going to be installed
                        Depends: libcheese7 (>= 3.0.1) but it is not going to be installed
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages."

The packages don't seem to want to install. Any input?

I am an Ubuntu novice. Please be specific with commands.

  • could you try installing those required package? run sudo apt-get install libglapi-mesa:i386 libcheese-gtk23 libcheese7 . then run sudo apt-get install libgl1-mesa-dri:i386 libgl1-mesa-glx:i386 libc6:i386. – adadion Dec 29 '15 at 7:23
  • If you use the graphical package manager, doesn't add the required packages automatically? – Max Kulik Dec 29 '15 at 8:25
  • I tried the 'sudo apt-get install libglapi-mesa:i386 libcheese-gtk23 libcheese7' and 'sudo apt-get install libgl1-mesa-dri:i386 libgl1-mesa-glx:i386 libc6:i386' but they give me errors, just like the one at the end of the initial question. – UberSteak Dec 31 '15 at 0:33

Original answer from "Steam Install Error on 14.04 Ubuntu 64bit"

Try this :

sudo apt-get install libc6:i386 

sudo apt-get install libgl1-mesa-glx-lts-trusty:i386

Then relaunch Steam
