You might have a DNS issue and not a certificate issue, so before you disable SSL verification in your Git shell you should rule out a DNS problem. Cases such as these have been mentioned in Q&A forums such as https-issues-possibly-related-to-dns. If you are using WSL on Windows as your terminal, then you can try running sudo echo nameserver 8.8.8.8 > /etc/resolv.conf and then issue the git commands to see if that makes a difference. This does not seem to be a permanent DNS fix (lasting only the lifetime of your terminal session), but it could help you determine whether it is a DNS issue and not a certificate issue. You could also check this document on configuring your network to use a public DNS. Again, this is only to help you determine if your DNS settings might need adjusting in order to help resolve the certificate issues.

修复SSL证书的特定错误问题:无法在git中获取本地颁发者证书

我在Let's Encrypt证书时也遇到了同样的问题。

一个网站与https我们只需要:

SSLEngine On
SSLCertificateFile /etc/letsencrypt/live/example.com/cert.pem
SSLCertificateKeyFile /etc/letsencrypt/live/example.com/privkey.pem
Include /etc/letsencrypt/options-ssl-apache.conf

但少不要脸的人说:

fatal: unable to access 'https://example.com/git/demo.git/': SSL certificate problem: unable to get local issuer certificate

要修复它，我们还需要添加:

SSLCertificateChainFile /etc/letsencrypt/live/example.com/chain.pem

为了避免完全禁用ssl验证或复制/破解git使用的捆绑的CA证书文件，您可以将主机的证书链导出到一个文件中，并让git使用它:

git config --global http.https://the.host.com/.sslCAInfo c:/users/me/the.host.com.cer

如果这不起作用，您可以只对主机禁用ssl验证:

git config --global http.https://the.host.com/.sslVerify false

注意:当ssl验证关闭时，可能受到中间人攻击。

在我的例子中，因为我已经为windows 7安装了ConEmu终端，它在C:\Program Files\Git\mingw64\ssl\certs.的安装过程中创建了ca-bundle

因此，我必须在终端上运行以下命令才能使其工作:

$ git config --global http.sslbackend schannel
$ git config --global http.sslcainfo /mingw64/ssl/certs/ca-bundle.crt

因此，我的C:\Program Files\Git\etc\gitconfig包含以下内容:

[http]
    sslBackend = schannel
    sslCAinfo = /mingw64/ssl/certs/ca-bundle.crt

另外，在安装Git时，我选择了与这里提到的相同的选项。

希望有帮助!

git config --global http.sslbackend secure-transport

(必须在更新到Big sssr后这样做)

问题是git默认使用“Linux”加密后端。

从Git for Windows 2.14开始，您现在可以配置Git使用内置的Windows网络层channel作为加密后端。这意味着它将使用Windows证书存储机制，您不需要显式地配置curl CA存储机制:https://msdn.microsoft.com/en-us/library/windows/desktop/aa380123(v=vs.85).aspx

执行:

git config --global http.sslbackend schannel

这应该会有所帮助。

在Windows上安装git时，使用通道是现在的标准设置，如果可能的话，建议不要通过SSH或更多的方式签出存储库，因为https更容易配置，而且不太可能被防火墙阻止，这意味着失败的几率更小。
