Answer by Lichi for git: rename local branch failed

I get into this issue too. The reason is that I didn't have any commit on this git repository.

When I run the command git branch -M main. I get the following error message.

error: refname refs/heads/master not foundfatal: Branch rename failed

After I add my first commit by the following command, all things work.

git add .git commit -m 'Init'
