nmap PortScannerError

[Gabbo28]

Hi,
I am running Warberry Pi on Raspberri Pi 3 B+ with Kali 4.19.93-Re4son-v8+.

Running warberry.py I always get the same error:

[+] Scanning for Windows Hosts ...

[+] Scanning for MSSQL Databases ...
[+] Scanning for MySQL Databases ...
[+] Scanning for Oracle Databases ...
Traceback (most recent call last):
