ipaddress.AddressValueError: '1.0.0.0/24' does not appear to be an IPv4 or IPv6 network.

I'm on fresh Ubuntu Server 20.04. The python-ipaddress is installed by the command:

sudo apt-get install -y python-ipaddress

But geolite2legacy.py returns the following error:

./geolite2legacy.py -i GeoLite2-Country-CSV.zip -f geoname2fips.csv -o GeoIP.dat

Database type Country - Blocks IPv4 - Encoding: utf-8

    ' a unicode object?' % address)
ipaddress.AddressValueError: '1.0.0.0/24' does not appear to be an IPv4 or IPv6 network. Did you pass in a bytes (str in Python 2) instead of a unicode object?

In order to solve this error I've made the following change:

git diff

Does this a correct way to solve that issue?

I made a similar change but:

   nets = [IPNetwork(unicode(row['network']))]

Disclaimer: I'm not a python dev, so this isn't guaranteed to be a foolproof solution.

Thanks, this fixed the issue I was having on CentOS 7

fyi: ran into this on python 2.7, goes away on python3.
