当涉及到git的高级操作时，我更像是一个新手。我使用博客框架Octopress来维护我的博客。虽然Octopress自2011年以来没有任何开发，但它很好地满足了我的目的，所以到目前为止我还没有想过要改变任何东西。
仅供参考，我的博客托管在Github Pages上。
今天，在工作在一个新的帖子，git状态显示以下消息:
On branch source
Your branch is based on 'origin/master', but the upstream is gone.
(use "git branch --unset-upstream" to fixup)
所有后续命令都重复相同的消息，如git add .， git commit -m 'message'和git push origin source。
这条信息是什么意思?
有什么东西坏了吗?
如果是，是什么?
我需要修理它吗?
如果可能的话，请给我一个pdf/网络文章，在那里我可以阅读这一点，并理解它的未来。
更多的细节:
bash-3.2$ git branch -a
* source
remotes/octopress/2.1
remotes/octopress/HEAD -> octopress/master
remotes/octopress/gh-pages
remotes/octopress/linklog
remotes/octopress/master
remotes/octopress/refactor_with_tests
remotes/octopress/rubygemcli
remotes/octopress/site
remotes/origin/source
如果还需要更多信息，请告诉我。谢谢。
Actually torek told you already how to use the tools much better than I would be able to do. However, in this case I think it is important to point out something peculiar if you follow the guidelines at http://octopress.org/docs/deploying/github/. Namely, you will have multiple github repositories in your setup. First of all the one with all the source code for your website in say the directory $WEBSITE, and then the one with only the static generated files residing in $WEBSITE/_deploy. The funny thing of the setup is that there is a .gitignore file in the $WEBSITE directory so that this setup actually works.
足够的介绍。在这种情况下，错误也可能来自_deploy中的存储库。
cd _deploy
git branch -a
* master
remotes/origin/master
remotes/origin/source
在.git/config中，你通常需要找到这样的东西:
[core]
repositoryformatversion = 0
filemode = true
bare = false
logallrefupdates = true
[remote "origin"]
url = git@github.com:yourname/yourname.github.io.git
fetch = +refs/heads/*:refs/remotes/origin/*
[branch "master"]
remote = origin
merge = refs/heads/master
但在您的情况下，分支管理员没有遥控器。
[core]
repositoryformatversion = 0
filemode = true
bare = false
logallrefupdates = true
[remote "origin"]
url = git@github.com:yourname/yourname.github.io.git
fetch = +refs/heads/*:refs/remotes/origin/*
你可以通过以下方法来解决:
cd _deploy
git branch --set-upstream-to=origin/master
所以，一切都像torek告诉你的那样，但可能需要指出的是，这很可能涉及到_deploy目录，而不是你的网站的根目录。
PS:使用带有git插件的shell(如zsh)来避免将来被这个东西咬伤可能是值得的。它将立即显示_deploy涉及不同的存储库。
