运行ubuntu 12.04 64位。我想跟随在结束写入的步骤此页面的标题下：compat的图书馆安装Android SDK中。我这样做是为了解决这个问题。但是当我运行第一个命令时
sudo dpkg --add-architecture i386
它失败并给出以下输出：
pkg: error: unknown option --add-architecture
Type dpkg --help for help about installing and deinstalling packages [*];
Use `dselect' or `aptitude' for user-friendly package management;
Type dpkg -Dhelp for a list of dpkg debug flag values;
Type dpkg --force-help for a list of forcing options;
Type dpkg-deb --help for help about manipulating *.deb files;
Options marked [*] produce a lot of output - pipe it through `less' or `more' !
如何成功运行此命令？
