Hi,
There is no official solution. You try two things for sed command failure,
- .config file is located in “/usr/src/linux-headers-/kernel-/”. So, you need to execute sed command there.
- If you don’t have success with step-1, directly update the default value of CPTCFG_IWLMVM_VENDOR_CMDS in backport-iwlwifi driver.
- Open “backport-iwlwifi/drivers/net/wireless/intel/iwlwifi/Kconfig.noupstream”
- Change y to n in below line,
config IWLMVM_VENDOR_CMDS
bool “enable vendor commands”
depends on IWLMVM
default n
