关于编译时FAILED: setup-jack-server 失败是什么原因

我固件编译环境和源码都配置正确，也编译成功固件并在RK3399PROD开发板上进行测试，运行正常，编译环境编译固件也正常。由于我的办公电脑是安装的WINDOWS10和Ubutun18双系统（不是在WINDOWS上安装的虚拟机），在电脑开机是选择启动那个系统。由于作功能测试，有两三个月没有开Ubutun系统并编译RK3399PROD的固件，这几天由于需要重新编译固件，在编译的过程中报错，编译不成功。不知道什么原因。也根据网络上的建议进行端口修改，修改

原来固件编译成功并经过测试运行正常，两三个月没有启动Ubutun系统并编译固件，现项目需要重新编译固件出现上面报错，固件编译不成功。不知是什么原因导致的。根据网络建议方法修改端口，也没解决问题。
