Android,设置Linux构建环境,libgl1-mesa-glx：i386包有未满足的依赖项

我正在尝试为AOSP建立一个 Linux构建环境.我有Ubuntu-12.04.4-desktop-amd64分配.我按照 here给出的说明做了一切.
我输入terminal命令来安装必要的包：

$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

然后我收到一条错误消息：

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.

所以合乎逻辑的做法是sudo apt-get install libgl1-mesa-dri：i386,然后得到以下消息：

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

我担心的是它将要拆除的包装.在我看来,如果我允许删除,我会松开我的桌面环境.

有人对此有什么想法吗？

$sudo apt-get install git gnupg flex bison gperf build-essential \
