warning: ignoring broken ref refs/remotes/origin/HEAD

Question

I encountered this recently when someone on my team deleted our old development branch from the remote. I ran this command to check the status of HEAD:

$ git symbolic-ref refs/remotes/origin/HEAD
refs/remotes/origin/old_dev

This command output the name of the old development branch, which no longer exists.

I fixed the warnings using this:

$ git symbolic-ref refs/remotes/origin/HEAD refs/remotes/origin/new_dev

(Where "new_dev" is a branch name. Replace it with the name of the branch you want HEAD to point to.)

This is a simpler solution than symbolic-ref.

Since you may have excluded the branch that origin/HEAD was initially pointed to.

1. List your remote branches with:

git branch -r

2. If it doesn't show in the results:

origin/HEAD -> origin/(something)

3. Just point it again with:

git remote set-head origin master

where "master" is the name of your primary (head) branch.

---

Running git branch -r again now shows origin/HEAD -> origin/(something) and the warning goes away.

Just run the command -

#replace the <branch name> with your main branch - master, main, etc.    
git remote set-head origin <branch name>

Enjoy!

Some problems arise after the local master renames main:

• git fetch: "fatal: couldn't find remote ref refs/heads/master";
• git branch -u origin/main main: "error: the requested upstream branch 'origin/main' does not exist";
• git remote set-head origin main: "error: Not a valid ref: refs/remotes/origin/main";
• git push -u origin main: "error: failed to push some refs to 'github.com:/.git'";
• git symbolic-ref HEAD refs/heads/main or git symbolic-ref refs/remotes/origin/HEAD refs/remotes/origin/main or git update-ref refs/heads/main main,
  • and then git branch -r: "warning: ignoring broken ref refs/remotes/origin/HEAD";

The solution to this problem:

1. git remote -v, copy git repository url
2. git remote rm origin, remove remote
3. git remote add origin <REPOSITORY_URL>, reset remote url
4. git fetch origin
5. git branch -u origin/main main, reset branch upstream
