Ubuntu 16.04-Gephi 0.9.1 无法运行

我第一次安装 Gephi 时遇到了一些问题，但后来问题解决了。然而，两天前，它决定停止运行，我找不到问题所在。我尝试了不同论坛上提供的解决方案，但都没有解决。它基本上在启动画面时崩溃。

    java version "1.8.0_131"
    Java(TM) SE Runtime Environment (build 1.8.0_131-b11)
    Java HotSpot(TM) 64-Bit Server VM (build 25.131-b11, mixed mode)

另外，输入

    sudo apt-get update

它返回

它比我想象的要简单得多：

    rm -r .gephi

并且解决了。
