制作时：
sudo git clone git@gitlab.mydomain.com:ws.git
我收到错误：

有什么问题？
公共克隆存在问题吗？我可以只克隆添加个人ssh密钥吗？
添加了个人ssh-key：
现在：

有什么问题？
此[SSH Key asks for password]不起作用
> sudo git clone --verbose git@gitlab.mydomain.com:ws.git
Cloning into 'ws'...
fatal: The remote end hung up unexpectedly
答案 0 :(得分：1)
从此处找到解决方案gitlabhq issue on github：
查看你的puma或unicorn服务器配置：
sudo nano /home/git/gitlab/config/puma.rb
读取一个绑定的网址（有趣的是端口 - 在我的情况下是9292 //我在一段时间之前将绑定变体从unix管道更改为http://0.0.0.0:9292）
更改gitlab-shell中的config.yml：
sudo nano /home/git/gitlab-shell/config.yml
重启gitlab服务：
sudo service gitlab restart
（我不知道，但我也重启了apache：sudo service apache2 restart）
完成的：
现在，只需从项目页面复制网址即可：
git clone your-gitlab-url
答案 1 :(得分：0)
我确实遇到了这个问题，只能通过反复试验找到答案。

事实证明，gitlab不喜欢2048位SSH密钥。我将SSH密钥更改为4096位，并且工作正常。我不知道这是sshd配置的结果还是什么，但它对我有用。
