当我尝试安装时sudo apt-get install steam出现此错误：

我研究了很多可能的解决方案，其中一个例子是：
sudo apt-get install libgl1-mesa-dri:i386
sudo apt-get install libgl1-mesa-glx:i386
这样做只会导致更大的错误：

分别是之前和之后
sudo dpkg --add-architecture i386
这没有什么区别。
即使是全新安装，问题仍然存在，所以我真的不知道该怎么办
我犹豫是否要安装任何主要的系统更新，因为它们可能会损坏我笔记本电脑的触摸板，因此我将其作为最后的手段，但说实话，在这一点上任何事情都是受欢迎的......
编辑：哎呀，看来更新真的是我唯一的选择。希望它不会像上次那样弄坏我的触摸板，否则我将不得不向 ubuntu 提出一个完全不同的要求……没什么进展
编辑 2：谢天谢地，它成功了！我进行了全面更新，之后它给了我一个不同的屏幕（也许对你们中的一些人有用，我不知道）
Steam needs to install these additional packages:

然后我就可以正常运行 steam 了，最棒的是：我的触摸板工作正常！感谢大家的回答，如果我浪费了大家的时间，我很抱歉

我用它来运行 PlayOnLinux，这是一个 WineFrontend。这里有一个链接，也许能帮助你决定如何在 Ubuntu 上运行它。https://gaming.stackexchange.com/questions/16751/how-do-you-get-your-steam-games-to-run-on-ubuntu-through-wine-or-something-simil
答案2
确保您已经启用“universe”和“multiverse”存储库。
sudo add-apt-repository universe
sudo add-apt-repository multiverse
sudo apt update
sudo apt install steam
更新：
您还需要确保自己已完全更新：
sudo apt full-upgrade
持续的依赖问题有时可以通过以下方式解决gdebi：
sudo apt install gdebi
此后，您可以尝试deb从官方 repo 安装最新版本：
wget http://repo.steampowered.com/steam/archive/precise/steam_latest.deb
sudo gdebi steam_latest.deb
虽然这可能无法完全解决您的问题，但它应该能更好地阐明依赖冲突。
你可以一直强迫自己，然后祈祷最好的结果：
sudo apt install -f steam
