Execute gnome-help, you can open the help panel, but there is no information, see the attachment for details.
The version of yelp is: yelp-40.3-1, I have done cross-validation and have ruled out the problem of yelp itself, but because I am not particularly familiar with yelp itself, and the final result is reflected by yelp, I still seek help here to see if Useful information can be obtained to further troubleshoot and locate the problem.
Any suggestions are welcome.
