问题出现了不久前：
$ git push origin source
To git@github.com:Loremaster/Loremaster.github.io.git
! [rejected] source -> master (fetch first)
error: failed to push some refs to 'git@github.com:Loremaster/Loremaster.github.io.git'
hint: Updates were rejected because the remote contains work that you do
hint: not have locally. This is usually caused by another repository pushing
hint: to the same ref. You may want to first integrate the remote changes
hint: (e.g., 'git pull ...') before pushing again.
hint: See the 'Note about fast-forwards' in 'git push --help' for details.
时，它突然想将其推送到主分支（这是错误的，我想将本地源分支推送到远程源分支）。我记得我以前没有这样的问题，但现在我遇到了。当我部署我的博客时，一切正常（它已部署到主服务器），但我根本无法更新我的源代码。解决这个问题的最佳方法是什么？
这里也是git remote
$ git remote -v
octopress git://github.com/imathis/octopress.git (fetch)
octopress git://github.com/imathis/octopress.git (push)
origin git@github.com:Loremaster/Loremaster.github.io.git (fetch)
origin git@github.com:Loremaster/Loremaster.github.io.git (push)
这是git config --get-regexp remote
$ git config --get-regexp remote
remote.octopress.url git://github.com/imathis/octopress.git
remote.octopress.fetch +refs/heads/*:refs/remotes/octopress/*
branch.source.remote origin
remote.origin.url git@github.com:Loremaster/Loremaster.github.io.git
remote.origin.fetch +refs/heads/*:refs/remotes/origin/*
和
$ git branch -avvv

git remote并不是这里唯一的因素。
git branch -avvv有助于查看哪个分支与远程跟踪分支相关联：它显示现在源与远程跟踪分支相关联origin/master而不是origin/source。
您可以使用以下命令重置本地分支source的远程跟踪分支：
git branch -u origin/source source
请参阅"使现有 Git 分支跟踪远程分支？
然后，如果git config push.default设置为 simple（对于 Git 1.9+），一个简单的git push（在 source 分支上签出时）就足够了。
