今天用git clone下代码，修改，push提交，发现以下错误
[root@localhost gocache]# git push origin master error: The requested URL returned error: 403 Forbidden while accessing https://github.com/zebozhuang/gocache.git/info/refs
查一下，原来是我用https clone代码,在.git下的remote url也会使用https,参考
http://stackoverflow.com/questions/7438313/pushing-to-git-returning-error-code-403-fatal-http-request-failed
在.git下修改config
url = ssh://git@github.com/zebozhuang/gocache.git
即可。
问题的实质是git的版本过低导致。参考
https://help.github.com/articles/https-cloning-errors/
问题解决！
----------------------------------------------Fri Apr 10 22:45:01 CST 201，出现新问题
git pull
There is no tracking information for the current branch. Please specify which branch you want to merge with. See git-pull(1) for details git pull <remote> <branch> If you wish to set tracking information for this branch y git branch --set-upstream-to=origin/<branch> master
也属于老版本问题，解决
git branch --set-upstream-to=origin/master master
