15.10 更新后，我无法玩 Minecraft 或 FTB

我之前用 Xubuntu 15.4 玩 Minecraft 还不错。昨天我更新到 15.10 后就无法在线玩了。以下是启动日志。我尝试重新安装 Minecraft 本身和 Java。我似乎遇到了 Feed the Beast（Minecraft 的 modpack 客户端）的另一个问题，它给出了以下错误：

Authlib checksum download failed, please check log for bad SSL 
certificates: javax.net.ssl.SSLHandshakeException: 
sun.security.validator.ValidatorException: PKIX path building failed: 
sun.security.provider.certpath.SunCertPathBuilderException: unable to
find valid certification path to requested target

以下是 FTB 启动器的另一个错误：

SSL handshake failed. Something might be altering SSL certificates
Certificates are not trusted by JVM certificate chain
Certificate chain will be printed in debug logging level
Authlib Download Failed

还有一个：

No usable authlib available. Please check your firewall rules and network 
connection. Can't start MC without working authlib. Launch button will be 
disabled.

需要说明的是，我没有使用防火墙，而且我拥有chmod +x所有 .jar 文件。我在多个 Minecraft 和 FTB 论坛上搜索过答案，但一无所获。

我认为这些问题可能是相关的，但比我更了解的人可能会证明我错了。

我将非常感激任何帮助。

谢谢！

编辑：一周没有回复后，我几乎放弃了。我仍然不知道该怎么办。

编辑：我已将oracle-java其删除并替换为open-jdk-8。现在我收到此错误：Recognized exception: the likely cause is a set of broken/missing root-certificates. Check your java install and perhaps reinstall it.

Unable to download remote file. Check your internet connection/proxy settings.
FATAL ERROR: net.minecraft.bootstrap.FatalBootstrapError: Unable to download while being forced
    at net.minecraft.bootstrap.Bootstrap.execute(Bootstrap.java:95)
    at net.minecraft.bootstrap.Bootstrap.main(Bootstrap.java:381)


Please fix the error and restart.

我稍微弄了一下，并在jre/lib/security/cacerts文件中添加了一个证书。这样我取得了一些进展，现在日志如下所示：

对我来说，这仍然看起来像是证书的问题，但说实话，我对这类事情不太了解。感谢您的帮助。我仍然迷茫。有没有人有任何从哪里开始呢？

好的，现在我得到了一些帮助，但我似乎无论如何都无法弄清楚如何做到这一点。我测试了以下版本的 Java：

  • Oracle Java 8

  • OpenJRE 8

  • Oracle Java 9

答案1

经过测试并与 FTB IRC 中的优秀人员合作后，我们成功了。我们做了一些改动（例如将 cacerts 链接到 java 的二进制文件中），但真正解决问题的是这个命令。请看这里 :)

sudo update-ca-certificates --fresh

答案2

答案是第一次就以正确的方式安装 Java，我尝试使用的主机上出现了问题，即使在部分安装之后，情况也是如此，我输入了错误的命令，一切都乱了套。我试图删除 ca-certificates 包，结果导致 Ubuntu 的一半都崩溃了……结果进行了数小时的重新配置，重新安装后，我无法再重现该问题。现在的解决方案是：我建议您删除每个 Java 安装，并手动清理 Java 文件夹。现在您可以安装一个名为 default-jre 的包，这应该可以解决问题。它的作用是安装一个名为 ca-cetficates-java 的包

sudo apt-get install default-jre

    The following extra packages will be installed:
  ca-certificates-java default-jre-headless fonts-dejavu-extra java-common libatk-wrapper-java libatk-wrapper-java-jni libgif4 libgnomevfs2-0       libgnomevfs2-common libsctp1 lksctp-tools openjdk-7-jre openjdk-7-jre-headless tzdata-java

然后它将带来 minecraft 运行所需的证书！就这么简单。

旧：我有同样的问题，它仍然需要更多的证书，但最新的错误日志没有说它尝试访问哪个站点。解决方案是让 java 接受任何证书。 https://stackoverflow.com/questions/1828775/how-to-handle-invalid-ssl-certificates-with-apache-httpclient

答案3

我遇到了这个问题，但 sudo update-ca-certificates --fresh 无法修复它。事实证明我的 icedtea 版本相对于我的 nss 版本已经过时了。

答案4

我可以通过使用 openjdk-8 而不是 openjdk-11 来解决该错误。要找出您使用的 Java 版本，请java --version在终端中输入。默认情况下，openjdk-java 安装在/usr/lib/jvm/java-$version-openjdk-$platform（其中 $version 是版本，例如 8，$platform 是平台，例如 amd64）。如果您在那里找到版本 8，您可以使用以下命令运行启动器/usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java -jar FTB_launcher.jar
