Git reference conflicts between branches (unable to update local branch)

Question

I\'m experiencing the following error while trying to git fetch a remote branch:

error: Ref refs/origin/remotes/my-branch is at s

Answer 1

I've found this error's cause:

Someone has created another branch with the same name, but different case.

What happened?

Git for windows isn't case sensitive. So, things just got crazy! Git couldn't distinguish one from another, mistaking the hash of each's head.

Solution:

Just cut the evil by its root. Wrong remote branch was deleted and evererything is nice as ever.
