我把那个bios的安全启动去掉就好了，可以参考这几个文章https://www.csdn.net/tags/OtDaQg4sOTY4MTQtYmxvZwO0O0OO0O0O.html https://community.silabs.com/s/question/0D51M00007xePiwSAE/cp210x-insmod-operation-not-permitted-in-ubuntu-18042-lts?language=en_US

Try disabling secure boot in your bios settings.

Signing the kernel module following https://ubuntu.com/blog/how-to-sign-things-for-secure-boot worked for me.
