Error when attempting to Scan, and HackRF is greyed out under spectrum

[mwk088]

Hello,

I have successfully installed sparrow-wifi and most of the dependencies into my Ubuntu 18.04 base docker image. I can bring up the GUI, however, when tasking I get the error below. Do you know what I am doing wrong or n additional package I may need? Exception in thread Thread-1: Traceback (most recent call last): File "/usr/lib/python3.6/threading.py", line 916, in _bootstrap_inner self.run() File "sparrow-wifi.py", line 499, in run retCode, errString, wirelessNetworks = WirelessEngine.scanForNetworks(self.interface) File "/opt/truearrow/6.3/sparrow-wifi/wirelessengine.py", line 596, in scanForNetworks result = subprocess.run(['iw', 'dev', interfaceName, 'scan'], stdout=subprocess.PIPE,stderr=subprocess.STDOUT) File "/usr/lib/python3.6/subprocess.py", line 423, in run with Popen(*popenargs, **kwargs) as process: File "/usr/lib/python3.6/subprocess.py", line 729, in __init__ restore_signals, start_new_session) File "/usr/lib/python3.6/subprocess.py", line 1364, in _execute_child raise child_exception_type(errno_num, err_msg, err_filename) FileNotFoundError: [Errno 2] No such file or directory: 'iw': 'iw'

In addition to the error, I also see the "HackRF sweep options" greyed out under the "Spectrum"

Thank you.

Hi mwk088. Easy fix. Looks like the iw tool isn't on your system. Try this: 'sudo apt install iw'. I generally also run Sparrow as root / sudo to make sure I have unrestricted access to the wireless adapter.

FileNotFoundError: [Errno 2] No such file or directory: 'iw'

sudo apt install iw worked for me.
