在服务器上运行 git clone xxxxx 下载程序时会报如下错误：
Warning: Permanently added ‘github.com,xx.xxx.xxx.xx’ (RSA) to the list of known hosts.
Permission denied (publickey).
fatal: Could not read from remote repository.
- 首先查看自己是否有公钥。运行指令
cat ~/.ssh/id_rsa.pub
如果有公钥则会看到一大段字符串:ssh-rsa…，这就是所谓的publickey；但是如果提示报错的话则说明没有公钥，此时你应当自己创建一个公钥，输入
ssh-keygen
然后一直回车就行，最后会生成一个矩形框框一样的东西，就说明公钥已经生成。
此时再运行指令
cat ~/.ssh/id_rsa.pub
就会看到那一大段字符串，就是publickey。
- 复制公钥。从ssh-rea开始一直到末尾xxx@xxxxxx前，选中，右键copy复制。
- 登录GitHub，点击右上角头像 –> settings –> SSH and GPG keys –> new SSH key –> title自己取名，key中粘贴publickey –> Add SSH key –> 成功.
- 再次运行代码 git clone xxxxxxxxxxxx. 成功运行。
- github连接远程仓库时出现Warning: Permanently added the RSA host key for IP address
- github配置公钥方法
问题2：
在服务器上运行 git clone https://xxxxx 下载程序时会报如下错误：
fatal: unable to access 'https://github.com/cocodataset/cocoapi.git/': GnuTLS recv error (-9): A TLS packet with unexpected length was received. WARNING: Discarding git+https://github.com/cocodataset/cocoapi.git#subdirectory=PythonAPI. Command errored out with exit status 128: git clone -q https://github.com/cocodataset/cocoapi.git /tmp/pip-req-build-o_aocosg Check the logs for full command output. ERROR: Command errored out with exit status 128: git clone -q https://github.com/cocodataset/cocoapi.git /tmp/pip-req-build-o_aocosg Check the logs for full command output. 解决方案：将命令行里的http改为git后重新执行。
