Best Answer

It is saying two things, "interface up or not permission" this means that you may need to:

sudo machanger

Or that the "Device or resource is busy".

Maybe something like:

sudo ifconfig wlan1 down
sudo airmon-ng stop wlan1

then run sudo machanger

and to get it up again.

sudo ifconfig wlan1 up
sudo airmon-ng start wlan1
