linux - 卡利Linux "could not resolve host github.com"错误

Question

我正在尝试下载 Discover Scripts 并且一直在使用 git clone <a href="https://github.com/leebaird/discover.git" rel="noreferrer noopener nofollow">https://github.com/leebaird/discover.git</a>作为我的命令。运行后返回:

git clone https://github.com/leebaird/discover.git
Cloning into 'discover'...
remote: Counting objects: 4217, done.
remote: Compressing objects: 100% (34/34), done.
error: RPC failed; result=56, HTTP code = 200 | 445.00 KiB/s     
fatal: The remote end hung up unexpectedly
fatal: early EOF
fatal: index-pack failed

所以我尝试更改我的代理:

<code>
export GIT_TRACE_PACKET=1
export GIT_TRACE=1
export GIT_CURL_VERBOSE=1</code>

这解决了围绕 RPC 失败错误的问题。但是，它现在给出了更多错误:

<code>

* Could not resolve host: github.com
* Closing connection 0
fatal: unable to access 'https://github.com/leebaird/discover.git/': Could not resolve host: github.com
</code>

所以我决定通过运行“ssh -v git@github.com”看看是否可以看到某种形式的改变`返回到:

我不确定如何继续或如何修复我的设置以允许克隆。我只需要解决这个问题，这样我就可以下载并继续。

Answer 1

1. 实际警告是 Couldn't find host github.com in the .netrc file .所以您可以解析“github.com”...它只是先在 netrc 中查找。

2. 您在第二个代码段中的真实问题是这样的:

   debug1: Trying private key: /root/.ssh/id_rsa debug1: Trying private key: /root/.ssh/id_dsa debug1: Trying private key: /root/.ssh/id_ecdsa debug1: Trying private key: /root/.ssh/id_ed25519 debug1: No more authentication methods to try. Permission denied (publickey).

3. 以下是一些故障排除提示:

   • https://help.github.com/articles/error-permission-denied-publickey/

   • SSH is looking in the wrong place for the public/private key pair on Windows

4. 坦率地说，这应该有效:git clone https://github.com/leebaird/discover.git

   这是我得到的，没有任何特殊标志或任何特殊配置:
