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

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。

我遇到了詹金斯的问题。当我更新证书时，我开始面临这个错误。

stderr fatal: unable to access server certificate verification failed. CAfile: /etc/ssl/certs/ca-certificates.crt

所以我已经在下面的文件中添加了我的新证书:

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

该文件的内容如下所示:

-----BEGIN CERTIFICATE-----
blahblha
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
blahblha
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
blahblha
-----END CERTIFICATE-----

只要在底部附上你的证书:

-----BEGIN CERTIFICATE-----
blahblha
-----END CERTIFICATE-----

导致这个问题的另一个原因可能是你的生物钟可能走错了。证书是时间敏感的。

查询当前系统时间。

date -R

您可以考虑安装NTP以从全局NTP池自动将系统时间与可信的internet时间服务器同步。例如，在Debian/Ubuntu上安装:

apt-get install ntp

Linux/Debian使用:

sudo cp /etc/ca-certificates.conf /etc/ca-certificates.conf.orig
sudo nano /etc/ca-certificates.conf
Change “mozilla/DST_Root_CA_X3.crt” in “!mozilla/DST_Root_CA_X3.crt” an save
sudo update-ca-certificates

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。
