pip3 install requirements fails in /ui (grpcio)

[greaterthanstar]

Kubuntu 19.04
Following the instructions exactly I get the following error during make. I narrowed it down to this part:

cd ui
sudo pip3 install -r requirements.txt

$:~/go/src/github.com/evilsocket/opensnitch/ui$ sudo -H pip3 --no-cache-dir install -r requirements.txt

I have Python 2 & 3 installed. Could that be the issue?

$python --version
Python 2.7.16

Seems to work if you comment out the top line in the requirements.txt file which mentions grpcio, and leave all the other lines intact. I guessed this from "Python 3 users do not need it", but I may be wrong.

I changed the version to 1.24.0 for both grpcio and grpcio-tools in ui/requirement.txt and successfully installed
grpcio==1.24.0
grpcio-tools==1.24.0

It did install.... can do above or just delete grpcio and the tools will pull in required grpcio depend.

Updating grpcio and tools actually fixed the build after I updated to Ubuntu 19, thanks @sudoerChris
