新安装的 Geogebra 打不开(大概 JDK 问题)

Newly installed Geogebra doesn't open (persumably JDK issue)

刚刚在我的 Ubuntu 16.04 上安装了 geogebra(使用普通的旧版 sudo apt-get install geogebra

当我尝试打开它时,我得到:

我想这与我的 JDK 有关,但我不知道该怎么做。我的 java -version 输出:

openjdk version "9-internal"
OpenJDK Runtime Environment (build 9-internal+0-2016-04-14-195246.buildd.src)
OpenJDK 64-Bit Server VM (build 9-internal+0-2016-04-14-195246.buildd.src, mixed mode)

谁能帮我解决这个问题?

Java 9 尚未正式发布,所以我非常怀疑是否有任何主要的 Java 应用程序正在使用它。我不知道你是怎么得到那个设置的,但我建议你安装 JDK 8 而不是

update-java-alternatives 应该可以作为命令使用(取决于您的 OS),但是在安装 JDK 8 之后,您可以 运行 和 select 它将 Java 8 设置为您系统的 Java 版本。

或者您可以自己编辑 PATHJAVA_HOME,但如果有更简单/更安全的方法,我不推荐这样做。
