Problem

Let’s suppose you have a repository with the following commit history:

5a998b8 (HEAD -> main) third commit
f318ad8 second commit
a187c18 first commit

By default, when you try to rebase all commits by running:

git rebase -i HEAD~3

The following error message will be shown:

fatal: invalid upstream 'HEAD~3'

Solution

To do that, simply run:

git rebase -i --root
