This error message occurs when you try to pull changes from a remote repository but there are conflicts with changes in your local repository that have not been resolved.

To fix this error, you need to resolve the conflicts in your local repository by editing the files that have conflicts, then adding and committing the changes.

Here are the steps to resolve the conflict:

1. Run the command git status to see which files have conflicts.
2. Open each conflicted file in your code editor and resolve the conflicts.
3. Once you have resolved the conflicts, add the changes to the staging area by running the command git add <file>.
4. Commit the changes by running the command git commit -m "Resolved conflicts."
5. Finally, try to pull again by running the command git pull.

If you still encounter the same error, repeat the steps above until all conflicts are resolved.
