I just installed NethunterOS, and Wifite fails at the monitor mode stage. If I set monitor mode first with start monstart-nh, wifite immediately fails with:

Looking for wireless interfaces...
error too many values to unpack
And then a few trace lines indicating a possible monitor mode issue.

If I run wifite with monitor mode off, and then select wlan0, it fails like this:

Select wireless interface (1-2):2
enabling monitor mode on wlan0... failed
failed

Error: Cannot find any interfaces in Mode:Monitor

Any ideas what this could be?
Thanks!
