How did you install Veil? (Apt, Clone from Github, etc.)

APT

Did you run the setup script?

YES

Pastebin link to error you are encountering (include console actions you took prior to error)

[NONE]

Expected behavior

complete the IP address instead of MAC address

Any additional info you want to tell me

When I change the interface to wlan0 from eth0 in /usr/share/veil/lib/common/completer.py, the completion works fine but when set back to eth0, it completes the MAC address.
So using this command, ip addr | awk '/state UP/ {print $2}' | sed 's/.$//' outputs the current working interface
hope this help you fix the issue.
