我正在关注有关安装 steam 的 debian wiki，但我不断遇到依赖性问题。
Debian 告诉我将sources.list 编辑为：
deb http://http.debian.net/debian/ jessie main contrib non-free
我的sources.list看起来像这样：
Debian GNU/Linux jessie/sid \n \l
#
deb http://ftp.uk.debian.org/debian/ jessie main contrib non-free
deb-src http://ftp.uk.debian.org/debian/ jessie main contrib non-free
#deb http://ftp.uk.debian.org/debian wheezy main
#deb http://security.debian.org/ wheezy/updates main non-free
#deb-src http://security.debian.org/ wheezy/updates main contrib non-free
# wheezy-updates, previously known as 'volatile'
#deb http://ftp.uk.debian.org/debian/ wheezy-updates main contrib non-free
#deb-src http://ftp.uk.debian.org/debian/ wheezy-updates main contrib non-free
我未解决的依赖关系如下所示：

29) libxxf86vm1:i386 [Not Installed]
30) steam:i386 [Not Installed]
31) zlib1g:i386 [Not Installed]
Leave the following dependencies unresolved:
32) libgl1-mesa-glx:i386 recommends libgl1-mesa-dri:i386 (>= 7.2)
我认为这可能与此有关，# dpkg --add-architecture i386但当我运行命令时似乎没有发生任何事情。
