The following error occurred:
Here are my operational procedures and solutions.
Solution
The author refers to the ROS installation performed by the Gu Yueju course at Station B. If you want to get started with ROS, you can also refer to this course. The specific configuration process is not the same as that in the course. Refer to the official ROS installation tutorial. The link is as follows :

You can also take a look at the installation process of Gu Yueju first to get a general understanding of ROS installation.
Refer to the process in the above link, I have a problem in the above steps.
I mainly refer to these two articles:

Combining the two articles, I used the searched IP to write the document mentioned in the link. In theory, it should work well, but it is still the same bug.
At this time, I remembered that some articles mentioned replacing wifi. After testing, the campus network and my mobile phone network are not working, but the network that is normally opened in the laboratory can be used.
I hope my debugging experience can help everyone.
