我正在尝试克隆
just went fully open-source的原子库,我遇到了一些麻烦.
原文链接：https://www.f2er.com/ubuntu/348198.html尝试克隆存储库会产生SSL错误：
wug@wugputer:/src/test$git clone https://github.com/atom/atom.git Cloning into atom... error: SSL certificate problem,verify that the CA cert is OK. Details: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify Failed while accessing https://github.com/atom/atom.git/info/refs fatal: HTTP request Failed
谷歌搜索表明这是一个失败的CURL调用,并且我可以设置一个环境变量来获取更多信息,但它没有显示任何特别有用的信息：

我在工作,proxy.wugcorp.com是我们的网络代理(预计会在那里).我上周就能克隆一些东西而没有任何问题.我也能够卷曲文件git抱怨没有做任何有趣的技巧：
wug@wugputer:/src/test$curl https://github.com/atom/atom.git/info/refs Please upgrade your git client. GitHub.com no longer supports git over dumb-http: https://github.com/blog/809-git-dumb-http-transport-to-be-turned-off-in-90-days
openssl还报告证书很好：
wug@wugputer:/src/test$openssl s_client -connect github.com:443 -CApath /etc/ssl/certs

但最奇怪的是,如果我在strace中运行它,原来的git clone调用将会重新运行.
wug@wugputer:/src/test$strace git clone https://github.com/atom/atom.git [lots of output snipped] [works correctly]
我不知道是怎么回事.为什么git对github.com的证书如此生气,当其他一切都没问题的时候？更重要的是,当我试图检查时,为什么问题会消失？
