对于Windows上的MINGW64 Git Bash用户

以管理员身份启动Git Bash 在MINGW64终端中运行: echo -n | openssl s_client -showcerts -connect yourserver.com: yourhttpgitlabport 2>/dev/null | sed -ne '/- begin CERTIFICATE-/，/- end CERTIFICATE-/p' >> /c/Program\ Files/Git/mingw64/ssl/certs/ca-bundle.trust.crt 以管理员身份关闭Git Bash 启动Git Bash(不是管理员) 在MINGW64终端中运行: $ git配置——global http。sslBackend schannel $ git配置——global http。sslverify真实

我知道已经有很多答案了。对于那些使用专用网络(如Zscaler等)的用户来说，如果需要更新rootcert，则可能会出现此错误。如果在Windows机器上使用WSL，这里有一个关于如何实现此更新的解决方案:

#!/usr/bin/bash

# I exported the Zscaler certifcate out of Microsoft Cert Manager.  It was located under 'Trusted Root Certification > Certificates' as zscaler_cert.cer.
# Though the extension is '.cer' it really is a DER formatted file.
# I then copied that file into Ubuntu running in WSL.

# Convert DER encoded file to CRT.
openssl x509 -inform DER -in zscaler_cert.cer -out zscaler_cert.crt

# Move the CRT file to /usr/local/share/ca-certificates
sudo mv zscaler_cert.crt /usr/local/share/ca-certificates

# Inform Ubuntu of new cert.
sudo update-ca-certificates 

不需要将git SSL验证设置为false。这是由于系统中没有所有的CA授权证书。大多数拥有真正SSL证书的人都缺少中间证书。

只需将中间证书全文(缺失CA和中间证书的全链)添加到

sudo gedit /etc/ssl/certs/ca-certificates.crt 

不运行update-ca-certificates即可工作。

对于手动生成的证书也一样，只需添加CA证书文本。

最后:Push successful:一切都是最新的

我搞砸了我的CA文件，而我设置goagent代理。不能从github拉数据，并得到相同的警告:

服务器证书验证失败。CAfile: /etc/ssl/certs/ca-certificates。crt CRLfile:无

使用Vonc的方法，从github获取证书，并将其放入/etc/ssl/certs/ca-certificates。Crt，问题解决了。

echo -n | openssl s_client -showcerts -connect github.com:443 2>/dev/null | sed -ne '/- begin CERTIFICATE-/，/- end CERTIFICATE-/p'
