Hello, i'm trying to build android N for my Nexus 5x, on Ubuntu 16.04 LTS. I've synced the source (for three days) and now i'm getting errors with .ninja files. Here's the log:

You've got a permissions issue that is preventing reading some files:

build/core/product_config.mk:239:
vendor/lge/bullhead/device-vendor.mk: Permission denied

Did you mix running as root and as the dehumanized users when syncing?
If so, you will need to chown everything back to your user, something
like:
sudo chown -R dehumanized ~dehumanized/aosp
