Ubuntu 18.04 启动 libreoffice 组件失败

重现步骤：

1. ps aux | grep soffice.bin | grep -v grep 查看是否有office进程，如果有就杀掉（我本地确定没有office进程了）
2. 进入kkFileView-3.5.1/bin 执行 ./startup.sh
3. 查看日志：

4. 再次查看office进程，并没有异常提示的49933的进程 NOTE：用openoffice 就没有这个上述问题

真的受够了 就没一个解决这个问题的~~~~难道看运气 能否运行？

centos7.8 按教程排错 什么都正常 就是报 启动office错误，开个鸟的源 跟没开一样 完全查不出原因
