Android, setting up a Linux build environment, libgl1-mesa-glx:i386 package have unmet dependencies

Question

I'm trying to setting up a Linux build environment for AOSP. I have Ubuntu-12.04.4-desktop-amd64 distributive. I do everything in accordance with the instructions given here. I typed in the terminal command to install the necessary packages:

$ sudo apt-get install git gnupg flex bison gperf build-essential \
  zip curl libc6-dev libncurses5-dev:i386 x11proto-core-dev \
  libx11-dev:i386 libreadline6-dev:i386 libgl1-mesa-glx:i386 \
  libgl1-mesa-dev g++-multilib mingw32 tofrodos \
  python-markdown libxml2-utils xsltproc zlib1g-dev:i386

then I get an error message:

The following packages have unmet dependencies:
 libgl1-mesa-glx:i386 : Depends: libglapi-mesa:i386 (= 8.0.4-0ubuntu0.7)
                        Recommends: libgl1-mesa-dri:i386 (>= 7.2)
E: Unable to correct problems, you have held broken packages.

So the logical thing to do is sudo apt-get install libgl1-mesa-dri:i386, however then get the following message:

The following packages will be REMOVED:
 libgl1-mesa-dri-lts-quantal libxatracker1-lts-quantal ubuntu-desktop xorg
 xserver-xorg-lts-quantal xserver-xorg-video-all-lts-quantal
 xserver-xorg-video-vmware-lts-quantal
The following NEW packages will be installed:
 libdrm-intel1:i386 libdrm-nouveau1a:i386 libdrm-radeon1:i386 libdrm2:i386
 libexpat1:i386 libffi6:i386 libgl1-mesa-dri:i386 libllvm3.0:i386
 libpciaccess0:i386 libstdc++6:i386

My concern is the packages it's going to REMOVED. Seems to me that if I allow the removal I loose my desktop environment.

Anybody have any thoughts on this?

Answer 1

I solved this problem. Do the following, install all packages except libgl1-mesa-glx:i386:

$ sudo apt-get install git gnupg flex bison gperf build-essential \
  zip curl libc6-dev libncurses5-dev:i386 x11proto-core-dev \
  libx11-dev:i386 libreadline6-dev:i386 \
  libgl1-mesa-dev g++-multilib mingw32 tofrodos \
  python-markdown libxml2-utils xsltproc zlib1g-dev:i386

Install libglapi-mesa-lts-saucy:i386 instead of libgl1-mesa-glx:i386:

$ sudo apt-get install libglapi-mesa-lts-saucy:i386

Now you have correct AOSP build environment and don't loose desktop environment.

Answer 2

Just leave out the troubling package and install the recommended one afterwards. Important is now to make sure, that your desktop is not missing after reboot. Here is what I did:

sudo apt-get install git gnupg flex bison gperf build-essential \
zip curl libc6-dev libncurses5-dev:i386 x11proto-core-dev \
libx11-dev:i386 libreadline6-dev:i386 \ libgl1-mesa-dev g++-multilib mingw32 tofrodos \ python-markdown libxml2-utils xsltproc zlib1g-dev:i386

then:

sudo apt-get install libgl1-mesa-dri:i386

and then:

sudo apt-get install ubuntu-desktop xserver-xorg
