Java 游戏 - Minecraft - 无互联网连接

我在玩一款名为 Minecraft 的 Sandbox 游戏时遇到了问题。它似乎无法连接到互联网，但其他应用程序（如 Mega Cloud 或 Steam）可以毫无问题地连接到它们的服务器。有什么办法可以解决这个问题吗？

我在 64 位版本的 Ubuntu 17.10 上运行。我的规格是：Gigabyte gtx 1050ti 8gb ddr3 ram AMD A10-7850k cpu 我通过 LAN 连接到互联网（482mbit/s 下载 - 237mbit/s 上传）

这是启动器日志：

Please fix the error and restart.

尝试运行：

    sudo update-ca-certificates -f

如果不起作用，请尝试

    sudo apt purge ca-certificates-java && sudo apt install ca-certificates-java

该问题是由于 Ubuntu（及其版本）附带的 ca 证书对于 Java 来说有点损坏而引起的，因此重新安装并重新加载它们有望解决问题。
