git clone xxx@xx 版本后，edit某文件，commit之后，点push,提示报错。

可能有以下原因：

1、权限不够，远程仓库的文件夹（比如/home/git）下面的文件所属用户非git用户，而默认的文件权限通常是644，那么当你用非git用户push的时候，肯定是权限不够的。

解决方法：进入远程仓库的上一级，查看git目录下所有文件的权限，比如:

cd /home/git
ls -al

更改git目下所有文件目录的文件主为git：

chown -R git.git /home/git/*

2、如果报错提示如下：

则进入远程仓库

cd /home/git/ssm.git

再执行如下命令

git config 'receive.denyCurrentBranch' warn
