Not quite. It is telling you that your "fixes" branch is behind
upstream's "master".  You need to do a "rebase" your "fixes" branch
instead (while having the "fixes" being the current branch):

    $ git rebase upstream/master

You may have some conflicts to resolve, particularly around
ChangeLog files.

Once that's done, do a "git show" to make sure your commit looks
exactly the way you think it should look (in particular, that
the "diff" contains exactly the changes you mean to push).
And then, once done, try the push command again.
