我似乎遇到了一个工作流程错误，Ubuntu 的生命周期结束了。我得到了下面的屏幕截图。所以我点击了升级...来升级它，然后什么也没发生。
然后我点击升级...但什么也没发生。
我用 Google 搜索后发现我应该运行 enter，do-release-upgrade才意识到这基本上是在运行同一件事。
christopherwork@Chris-Gaming-Linux:~$ do-release-upgrade
Checking for a new Ubuntu release

听起来好像当我单击“升级”时...它实际上正在运行 do-release-upgrade，然后默默退出？无论如何，这非常烦人，似乎是一个需要修复的明显错误。
