Aaron,

Looks like your git repo is /home/nothim/src/edk2. The build is trying to cache some info in Conf/.cache and it is getting a permission error? Seems like a permission problem on your end? You can also try passing --no-cache  to the build command to turn this feature off? 

Thanks,

Andrew Fish
