我最近安装了一个软件包，导致电脑崩溃，但忽略了它会删除操作系统的很大一部分（Ubuntu 22.04.2 LTS）。虽然我已经恢复了由此错误造成的大部分损害，但在尝试启动 Steam 时遇到了问题。它尝试安装依赖项，但操作如下：
Steam needs to install these additional packages:
libc6:amd64 libc6:i386 libegl1:amd64 libegl1:i386 libgbm1:amd64 libgbm1:i386 libgl1-mesa-dri:amd64 libgl1-mesa-dri:i386 libgl1:amd64 libgl1:i386 steam-libs-i386:i386
Press return to proceed with the installation:
.........W: https://hub.unity3d.com/linux/repos/deb/dists/stable/InRelease: Key is stored in legacy trusted.gpg keyring (/etc/apt/trusted.gpg), see the DEPRECATION section in apt-key(8) for details.

requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created

值得注意的是（或者可能不是），我记得安装的 libglx 或相关软件包首先使计算机 beaned。我当时正漫不经心地试图解决“损坏的软件包”问题，以修复另一个应用程序。另外，我不确定为什么在前几行中会出现对 Unity3D 的引用 - 这可能是个问题吗？谢谢！
编辑：我尝试手动安装列出的依赖项，但它们显然最终都依赖于 libglapi-mesa：i386，这要求我卸载必要的系统组件并重复我刚刚尝试恢复的操作……我尝试了各种方法来解决“持有损坏的包裹”但到目前为止没有成功。

我在我的系统上遇到了几乎相同的问题，我通过清除 oibaf PPA 解决了该问题：
sudo ppa-purge ppa:oibaf/graphics-drivers
ppa-purge如果尚未安装，您需要安装。
我在上面的日志中看到版本号中有“oibaf”，因此看来您在某个时候添加了此 PPA 并使用了其中的软件包。我怀疑该 PPA 和 Ubuntu 标准软件包之间最近出现了一些冲突。
