Hi, I installed upnpy, and ran the script from you example:

import upnpy

upnp = upnpy.UPnP()

# Discover UPnP devices on the network
# Returns a list of devices e.g.: [Device <Broadcom ADSL Router>]
devices = upnp.discover()

# Select the IGD
# alternatively you can select the device directly from the list
# device = devices[0]
device = upnp.get_igd()

and on line 7 I get the following error:

I get a different error but another issue with upnp.discover():

Same error here on Linux Mint 20.1.

I was able to recreate all of these errors. Arch Linux (20210819). Python v3.9.6 UPnPy v1.1.8 installed with Pip.

Raising this from the dead, you can search for just IGDs with upnp.discover(ST='urn:schemas-upnp-org:device:InternetGatewayDevice:1')
