Hello,
Did you download the version:
RASPBIAN STRETCH WITH DESKTOP ?
I advise you to see this too: https://forum.magicmirror.builders/topic/4596/help-to-install-magicmirror
Good luck

These are not errors but known warnings. What is your problem, doesn’t it work and what doesn’t work because this is probably not a blocking installation error.
