Hello,

Recently I changed one of my repo's origin URL from gitlab to github.  After this switch, I start getting:

  warning: refname 'HEAD' is ambiguous.

messages when I use 'git status'. I check various things if I have tags/branches to blame but cannot find anything:

* git show-ref | grep -i head -> nothing suspicious

* find . -name HEAD | grep -v modules -> only .git/logs/HEAD and .git/HEAD

* git branch -a | grep HEAD -> nothing

Do you have any suggestions for a possible fix to this?

Thanks, Caglar

Are you sure? You don't have a ref called "HEAD"? Just "HEAD".

I don't see just "HEAD".  "git show-ref | grep HEAD" doesn't show anything if that's what you mean.

Thanks, Caglar

This is empty as well.

This is empty output also.

Both 'grep HEAD .git/packed-refs' and 'git for-each-ref | grep HEAD'  commands return nothing and still 'git status' is complaining about ambiguous HEAD.

Thanks, Caglar

Is it possible for you to tar up your .git directory and share it (either publicly, or privately to individual developers)?

Are you on a case-insensitive filesystem? Does `find .git -iname head -print` report anything that is not named uppercase HEAD?
