我有Ubuntu 18.04，未直接安装但已从16.10升级，这台计算机有一段时间没有使用Steam（可能是自18.04升级之前就不记得了），这导致了问题，并在一段时间后在互联网上寻找可能的解决方案的想法，我不得不承认失败。
我尝试了sudo apt-get autoremove / update / upgrade / dist-upgrade系列，但是它什么也没做。
编辑：我还完成了sudo apt-get clean和sudo apt-get install -f。
我还尝试通过删除.steam /和.local / share / Steam /来完全卸载。
我知道简单地手动安装软件包的方法，但这对我也不起作用。观察：
$ sudo apt install steam

在这一点上，我真的不知道该怎么办。尤其是针对“要安装8.3.0-16ubuntu3〜16.04”这一行。我有Ubuntu 18.04。为什么要安装16.04版中的内容？
为完成而再尝试一次：

并包含gcc-8-base：i386不会执行任何操作。
我如何中断我的Ubuntu安装？

尝试了所有顶级Google解决方案。他们都没有为我工作。
在this答案中出现，描述了我们如何重置损坏的程序包。
首先备份文件/var/lib/dpkg/status。然后清除该文件的所有内容。
然后运行sudo apt install steam。它可能会提示您是否存在已存在的文件并将被覆盖。最好检查文件内容中的差异。就我而言，我决定使用软件包维护者本身的软件，而不是我自己的软件。
蒸汽安装平稳。没有得到任何未满足的依赖项错误。
当我尝试开始工作时，遇到关于glxchoosevisual failed的错误。为此，我不得不安装libnvidia-gl-450:i386库。请注意，就我而言，我的nvidia驱动程序版本为450，因此使用了该版本。您需要在这里使用您的版本。而已！然后Steam启动正常。
在这里共享它以防他人。

检查是否已启用restricted和universe存储库。
您还可以运行：
这将从软件包中清除本地存储库，以便将其再次下载
apt-get clean
这是重新安装损坏的软件包
apt-get -f install
