You are not using Armbian.  You have downloaded software from a site that is a fork of Armbian and uses the Armbian name without permission.  They do not participate in Armbian development, nor do they participate in these forums.  We can't help you here as we don't produce the code you are running.  You need to log your question with those you downloaded your software from.
