warning: refname 'HEAD' is ambiguous

I am new to Git and I seem to have one branch too many if I execute the following command:

warning: refname 'HEAD' is ambiguous.

I get the following output:

warning: refname 'HEAD' is ambiguous.
From github.com:dagda1/hornget
 * branch            master     -> FETCH_HEAD
warning: refname 'HEAD' is ambiguous.
warning: refname 'HEAD' is ambiguous.

If I execute git branch -a

I get the f开发者_如何学Pythonollowing:

HEAD
* master
remotes/emmekappa/master
remotes/origin/HEAD -> origin/master
remotes/origin/master

I am confused by the remotes/origin/HEAD -> origin/master.

What is this and how can I get rid of the ambiguous branch.

I got to this stage by performing a merge where I think I added the ambiguous branch.

The problem is that you have a branch called HEAD which is absolutely dangerous, since that's the symbolic name for whatever branch is the current branch.

Rename it:

git branch -m HEAD newbranch

then you can examine it and decide what to do (delete it, or save under a descriptive branch name)

(The origin/HEAD remote branch is not a problem)

---

Also, this will delete the branch, if you just don't want it.

git branch -d HEAD

Use a capital -D to force the deletion:

git branch -D HEAD

---

If you have created a tag named HEAD using...

git tag HEAD

...you can just delete that tag using:

git tag -d HEAD

See this case: kerneltrap.org/git-tag HEAD

---

Check references available in your git repository. You will observe two HEAD in your repository. This makes your branch with refname HEAD ambiguous.

git show-ref

Solution:

• Rename the branch

  git branch -m HEAD <new_branch_name>
  

  OR

• Delete the branch

  git branch -d HEAD
  

---

This means that you have a branch named "head". I had the same issue, I solved by doing the following command.

git branch -d head
