Problem:
insmod: ERROR: could not insert module MODULENAME.ko: Required key not available
Solution:
1) sudo yum install mokutil
2) sudo mokutil —disable-validation
3) When executed, the terminal will let you set up 8-16 digit password (after you do, do not forget Oh ~)
Next, restart the computer, a blue screen (do not be nervous, press any key to enter the selection interface :–)), options are as follows:
– Continue boot
– Change Secure Boot state
– Enroll key from disk
– Enroll hash from disk
to select –>Change Secure Boot state<– , next in line before you enter the password.
requiresEnter password character 7, Meaning that the password bit 7 (this point to note!).
4) enter –> Disable Secure Boot selection <– screen,
select yes (Do not simply press Enter, this would be lost, only to start all over again!).
5) returned to the next screen beginning interface, reboot selection, re-enter the system
