The author encountered issues while uploading code to their GitHub repository, likely due to modifications made to the README file. After researching, they found a solution that involved backing up local files, restoring them, and then re-uploading. The problem seemed to stem from editing the README locally, which they realized should be avoided.

Here's the thing, some time ago I tried to create a GitHub repository to record the code I wrote during my learning process, and recently I frequently encountered the following issue when uploading.

Then after entering git pull, this situation would occur.

While writing this article, I realized it might be because I modified the readme file, but the solution I proposed is not this.
At that time, I searched for a while and finally found the solution at https://blog.csdn.net/L_smwy/article/details/121400574
The method used was solution two, but first, I backed up some things locally.

Then I put the backed-up items back and re-uploaded, and that solved the problem.
It seems that the issue was likely caused by modifying the readme file locally. I made the change because I noticed that the readme I downloaded was missing a line compared to what was written on GitHub, but it seems this thing shouldn't be modified locally.
