无法安装 Steam

我在使用 Steam 安装新的 Ubuntu 时遇到了问题。当我发出下面的“install steam”命令时，它说我缺少软件包。

user@test-desktop:~$ sudo apt-get install steam
Reading package lists... Done

Some packages could not be installed. This may mean that you have

The following information may help to resolve the situation:

The following packages have unmet dependencies.
 steam:i386 : Depends: libgl1-mesa-dri:i386
              Depends: libgl1-mesa-glx:i386
E: Unable to correct problems, you have held broken packages.

然后，当我尝试获取一些丢失的包时，它表明我依赖更多的包，如下所示。

user@test-desktop:~$ sudo apt-get install libgl1-mesa-dri:i386

E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.

我一定是在这里做错了什么。有人可以告诉我该怎么做吗？

仅供参考，我也很不高兴地执行了以下命令：

sudo apt-get autoremove
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade

根据建议，我也尝试过：

user@test-desktop:~$ sudo apt-get install ia32-libs
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package ia32-libs is not available, but is referred to by another     package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
  lib32z1 lib32ncurses5 lib32bz2-1.0

E: Package 'ia32-libs' has no installation candidate
