fatal: The upstream branch of your current branch does not match the name of your current branch

問題

After doing a checkout of the remote branch releases/rel_5.4.1 using the Git GUI, I'm seeing this unexpected error message when I try to push:

fatal: The upstream branch of your current branch does not match
the name of your current branch.  To push to the upstream branch
on the remote, use

    git push origin HEAD:releases/rel_5.4.1

To push to the branch of the same name on the remote, use

    git push origin rel_5.4.1
 

I don't know what Git is talking about. I probably want to push to origin releases/rel_5.4.1 since that's the branch which I checked out. So neither option seems correct to me.

git status says I'm on branch rel_5.4.1.

Here is the branch as it appears in my .git/config:

[branch "rel_5.4.1"]
    remote = origin
    merge = refs/heads/releases/rel_5.4.1
 

What is going on?

回答

To allow to push to the tracking branch on a per-git basis, thus make git pull and git push symmetric, use

git config push.default upstream

Note: To globally set this for all of your gits, use git config --global push.default upstream
However it is probably better to leave it to git config --global push.default simple
