It looks like the DCO signature is still unresolved. You need to execute git rebase HEAD~6 --signoff on your local branch, then git log check the commit record to see if all your commits are signed. After adding them all, then execute the git push --force-with-lease origin master command, which should solve the problem.

Finally I found out the problem.sorry for so many ugly commit.

I found that some pictures have been updated in this PR, but I don’t quite understand what has been updated. Could you please describe it?

yes it's weird.I have done nothing to those images.I fork and clone the repo and go directly to modify the "runtime" file.But those images is shown to be modified. Maybe it's because of mode of the files.

How about do not select these image files when git add?
