我想从Docker镜像运行Ubuntu SDK（Qt Creator变体）。除非我尝试使用模拟器或真正的手机/设备，否则它的工作非常好。这需要安装一个新的 Kit （armhf，i386），它在运行单击窗口中出现以下错误而失败。
Error getting authority: Error initializing authority: Could not connect: No such file or directory
---Click exited with errors, please check the output---
当我尝试从本机Ubuntu创建一个新工具包时，此操作会要求我插入sudo-password。 Docker镜像不会发生这种情况（我尝试安装gksu，因此，docker用户不需要sudo-password）。
这里有什么问题？
这是我创建的Dockerfile：
