Hi ,

I have just fresh the latest image to the device.

after ssh to the device as root, then I execute the commands below:

#echo 0 > /sys/kernel/security/digsig/enabled

it always return :
sh: write error: Operation not permitted

# ls -l /sys/kernel/security/digsig/enabled
-rw------- 1 root root 0 Jan 1 08:18 /sys/kernel/security/digsig/enabled

any ideas about it ?

Thanks

login as root ( sudo gainroot ) and then try that command.

you can also change rights to give executable rights for that file

chmod 777 /sys/kernel/security/digsig/enabled
