: ZSH seems to be causing the problem, switch to bash

If you had cloned the device tree and
brunch device shows
if device not found error then, check the device tree version, it may be the issues
eg device tree for lineage-16 may not work for lineage-15

net/Kconfig:80: can't open file "net/wireguard/Kconfig"
These type of error failed can occured if the scripts/{fetch_wireguard} exit with error, so you need to update that script And search for that latest script to download wireguard in other's device kernel file.

Sometimes you may get error like print << something >> files.py
That may be due to invalid python version, use python2 as your environment

Basically, download the kernel source to something like kernel// and add two Makefile variables into BoardConfig:
TARGET_KERNEL_SOURCE := TARGET_KERNEL_CONFIG := <name of defconfig from /arch//configs>

This happens because, I also have those defination in common tree.
So, remove that declaration from one of them. either from main device tree or from the common-tree.

Chomod -R 777 * for the whole kernel folder.

Also seems like my .repo folder was owned my other local user in my laptop .
So, I need to Chomod -R 777 * .repo folder and
also the entier lineage source code.
