我怎样才能解决一个问题；找不到请求目标的有效证书路径；使用conda安装的Java时出错？

我昨天使用了这个命令，它工作得很好。我可能安装了不同的perl或ava，但我不确定这会导致错误。我看过StackOverflow上的其他示例，但它们似乎适用于web浏览器

如何使用我的条件在远程服务器上修复此问题？

服务器关闭了。现在可以了。说明。

检查此链接。嗨@Sambit谢谢你的链接。我对Java和OpenSSL的了解有限，但我正在努力理解解决方案。看来问题是我没有合适的证书。这些是Java还是OpenSSL证书（如果这是一个愚蠢的问题，请道歉）？要在linux服务器上修复此问题，最简单的修复方法是使用以下工具：？我知道如何找到我的$HOSTNAME，但如何获取系统密钥库的

路径

和

端口

？如果您没有证书，没问题，您可以跳过它，为此我提供了链接。如果你发布代码，人们可能会帮助你。服务器没有关闭。您建立了与它的TCP连接，启动了与它的SSL握手，收到了来自它的证书，但未能与证书建立信任关系。如果服务器关闭，这一切都不可能。它不工作，我问工具的开发人员，他们说服务器关闭了。第二周，当服务器备份时，我再次尝试，它成功了。我不能复制这个，因为服务器已经启动了。他们告诉你什么无关紧要。如果服务器关闭，它就不可能向您发送证书。你会得到“连接被拒绝”或连接超时，而不是所有这些。那么我应该删除这篇文章吗？我想是的。答案是一式两份的，即使是真的，这个答案也帮不了任何人。与开发人员进行聊天也很合适。真正发生的是他们修复了证书。
