卸载之前正在运行的7.4安装后，刚刚安装了Netbeans 8.0.2。
jdk已正确设置并在设置时指示，安装成功完成（尽管没有像Netbeans 7.4中那样安装启动快捷方式）。
现在我发出
/usr/local/netbeans-8.0.2/bin/netbeans
并且脚本默默地搅拌几秒钟，然后返回时没有任何错误，也没有显示任何内容。
/usr/var/log/syslog显示没有错误。
编辑：发现里面有Netbeans的日志文件
〜/的.netbeans / 8.0.2 /变种/日志
它显示以下错误：

确定Ubuntu 64位系统与安装的JDK 32位之间存在问题。
一个简单的
apt-get install libxtst6:i386
解决了丢失的库。我的库是64位版本：
locate libXtst
/usr/lib/x86_64-linux-gnu/libXtst.so.6
/usr/lib/x86_64-linux-gnu/libXtst.so.6.1.0
