我有一台装有Ubuntu 16.10的计算机（yakkety），它可以完美地运行javafx应用程序。但是，即使我具有相同的openjfx软件包（8u102-b14-1），当我尝试在另一台具有ubuntu 18.10（宇宙）的计算机上运行相同的应用程序时，却遇到此异常。其他openjfx仿生软件包也不起作用。

有人知道如何解决这个问题吗？
最佳答案
在ubuntu 18中，我将openfx，libopenjfx-java，libopenjfx-jni降级：
sudo apt-get install libopenjfx-java = 8u161-b12-1ubuntu2 libopenjfx-jni = 8u161-b12-1ubuntu2
须藤apt install openjfx = 8u161-b12-1ubuntu2
