所以我是 ubuntu 新手，我不确定我是否做错了什么。每次我尝试加载 steam，它都会更新然后关闭。如果我尝试通过终端运行它，会发生这种情况：
benjy@Bens-UL:~$ steam
Running Steam on ubuntu 20.04 64-bit
STEAM_RUNTIME is enabled automatically
Pins up-to-date!
Steam client's requirements are satisfied

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