我正在尝试连接到我拥有的新 Minecraft 服务器(也来 self 拥有的客户端)。这是带有 Java 10 和最新 Minecraft 1.12 服务器的全新 Ubuntu 18.04 安装。

在连接期间，JRE 正在建立到身份验证服务器的连接，并且整个连接(从 Minecraft 服务器的角度来看)以 

[09:06:57] [User Authenticator #4/ERROR]: Couldn't verify username because servers are unavailable
[09:06:57] [Server thread/INFO]: com.mojang.authlib.GameProfile@949cab4d[id=<null>,name=TheNameOfTheUser,properties={},legacy=false] (/10.1.1.19:                                      41433) lost connection: Authentication servers are down. Please try again later, sorry!

身份验证服务器肯定没有关闭，我跟踪了连接并在网络转储中看到

问题出在第 105 帧，那里发生了 Internal Error。由于游戏是用 Java 编写的，我认为这与 Java TLS 实现很相似，这个“内部错误”实际上可能意味着更多？

作为可能的原因之一，我重新安装了 Java 证书 (update-ca-certificates -f)，但没有成功。

最佳答案

感谢@gusto2 的提示

这最终成为 Ubuntu 18.04 中的一个错误。详情在another SO answer , TL;DR 解决方案是以 root 身份运行

# /usr/bin/printf '\xfe\xed\xfe\xed\x00\x00\x00\x02\x00\x00\x00\x00\xe2\x68\x6e\x45\xfb\x43\xdf\xa4\xd9\x92\xdd\x41\xce\xb6\xb2\x1c\x63\x30\xd7\x92' > /etc/ssl/certs/java/cacerts

# /var/lib/dpkg/info/ca-certificates-java.postinst configure
