我通过多元宇宙存储库安装了 steam。但是尝试启动它时客户端不会显示。首次启动时，它会更新 steam，但完成后不会弹出 steam 客户端，每次启动 steam 都会导致直接退出。
从终端运行时，它将记录：
$ steam
Running Steam on ubuntu 18.04 64-bit
STEAM_RUNTIME is enabled automatically

Looks like steam didn't shutdown cleanly, scheduling immediate update check

我觉得很困惑，因为似乎没有记录明显的错误。
我~/.steam/steam/appcache首先删除了我的，然后清除了整个~/.steam/文件夹，但无济于事。
运行 16.04 时运行良好。
我如何启动 steam 客户端？
