====== solving your branch is ahead problem ======
If you are using a public repository and have messages where your branch is ahead of 'origin/master' by xx commits, this can be because someone has done a rebase or reset --hard on that branch, thus removing commits.  Even a git pull will not update your branch.  You can make your branch match the remote like this (substitute master with your branch name if necessary):<code>
git reset --hard origin/master

  HEAD is now at blah blah
</code>
