检查你的系统时钟，

美元的日期

如果不正确，证书检查将失败。要纠正系统时钟，

安装NTP

时钟应该自动同步。

最后再次输入clone命令。

最后，添加http。Sslverify到你的.git/config。

[core]
    repositoryformatversion = 0
    filemode = true
    bare = false
    logallrefupdates = true
[remote "origin"]
    url = https://server/user/project.git
    fetch = +refs/heads/*:refs/remotes/origin/*
[branch "master"]
    remote = origin
    merge = refs/heads/master
[http]
        sslVerify = false

sudo apt-get update
sudo apt-get install apt-transport-https ca-certificates -y 
sudo update-ca-certificates

对我有用。

当我试图在Dockerfile中克隆git时，我的工作是获取SSL证书并将其添加到本地证书列表:

openssl s_client -showcerts -servername git.mycompany.com -connect git.mycompany.com:443 </dev/null 2>/dev/null | sed -n -e '/BEGIN\ CERTIFICATE/,/END\ CERTIFICATE/ p'  > git-mycompany-com.pem

cat git-mycompany-com.pem | sudo tee -a /etc/ssl/certs/ca-certificates.crt

我在GitLab服务器上遇到了这个问题。通过cmd更新Linux的可信CA列表后解决了这个问题:

sudo apt-get install --reinstall ca-certificates

以下是步骤:

git跟踪返回如下错误:

 GIT_CURL_VERBOSE=1 GIT_TRACE=2 git clone https://mygitlab
...
...

* SSL connection using TLS1.2 / ECDHE_RSA_AES_256_GCM_SHA384
* server certificate verification failed. CAfile: none CRLfile: none
* Closing connection 0
**fatal: unable to access 'https://mygitlab/some.git/': server certificate verification failed. CAfile: none CRLfile: none**

查看git服务器的CA Issuer:

echo -n | openssl s_client -showcerts -connect yourserver.com:YourHttpGilabPort \
  2>/dev/null  | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' \
  | openssl x509 -noout -text | grep"CA Issuers" | head -1
...
...

CA Issuers - URI:http://r3.i.lencr.org/

为什么r3.i.lencr.org不可信?我尝试更新CA列表，它工作。

我做了什么来解决这个问题在终端(Ubuntu 18.04):

openssl s_client -showcerts -servername www.github.com -connect www.github.com:443

我得到了两个证书块。我将证书块复制到我的证书文件/etc/ssl/certs/ca-certificates.crt。
