@Speike 你可以继续install,应该没影响，不放心可以运行一下一键安装的一键换源。

@小鱼借个帖子，一键安装后，进到docker里边运行
ros2 run turtlesim turtlesim_node
错误打印：
qt.qpa.xcb: could not connect to display
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, xcb.

@卜上人间在主机端运行 xhost + 应该就可以了
