我是使用 Ubuntu 20.04 的新手。我正在学习 Linux 模块和驱动程序开发。我试图在内核中插入模块,但出现以下错误:
insmod: ERROR: could not insert module hellomod.ko: Invalid module format
以下是“dmesg”的结果:
[ 1311.552922] hellomod: loading out-of-tree module taints kernel.
[ 1311.552976] hellomod: module verification failed: signature and/or required key missing - tainting kernel
命令的结果如下mokutil
:
$ mokutil --sb-state
This system doesn't support Secure Boot
