I created a local repo with git remote origin https:////....
Then, in that local repo, I made a new text file → git add newfile.txt → git commit -m "..." → git pull origin main → ERROR!
"refusing to merge unrelated histories".
What are unrelated histories?
What are related histories?
I think you have committed in the remote repository, and when you pull, this error happens.
Use this command:
git pull origin main --allow-unrelated-histories
git merge origin origin/main
