Git - how to remove branch from checkout autocomplete

Question

I've deleted some local branches via git branch -d branchname, but they are still exist in autocomplete (when I put git checkout, then press tab key, I see all deleted branches in list).

I've tried to make git gc and git prune, but nothing changes.

If you are sure that you do not want the branch, you can remove it from your local and the remote like this:

$ git branch -D branchname
$ git push origin :branchname

Then it will stop appearing in autocomplete results.
