$ lsmod| grep tailm* 如果没有信息,说明驱动没装好。

可能性 1) 软件安装时驱动安装没有允许权限,所以驱动没装起来。确认sudo用户有root权限,或者尝试用root安装;
2) 服务器需要装 gcc make 和 kernel-devel包;
3) linux 内核升级了 lockdown 功能,导致签名验证不过的内核模块在安装时会报:
insmod: ERROR: could not insert module xxxxxxxx.ko: Operation not permitted; 查看内核 lockdown 状态: dmesg | grep secureboot
dmesg | grep lockdown
会打印相应的 lockdown 开启显示信息

解决方法:进入 BIOS,关闭Secure Boot
