来自apt存储库的Geogebra在ubuntu 18.04上无声地死掉
今天我跑了
sudo apt install geogebra geogebra-gnome 在股票ubuntu 18.04。 通过gnome启动器或终端运行地理代数会启动启动屏幕，然后它会静默终止。
以下是在终端中运行它的看法：

这是终端提到的日志文件

我为java或geogebra运行ps ax grepping，似乎没有运行。 有任何想法吗？
由于我意识到geogebra的apt repo版本很古老，我从https://wiki.geogebra.org/en/Reference:GeoGebra_Installation下载了最新版本
自18.04以来原生64位（至少我的版本）。 我下载了：
geogebra-classic_6.0.471.0-201805301433_amd64.deb
然后我删除了apt安装
sudo apt remove geogebra geogebra-gnome sudo apt autoremove
然后我安装了gdebi来帮助解决foriegn .deb的依赖关系
sudo apt install gdebi-core
并使用gdebi安装
sudo gdebi geogebra-classic_6.0.471.0-201805301433_amd64.deb
虽然命令行现在是geogebra-classic，但它运行得很干净。
