Hello, could you try with
sudo pip install paho-mqtt
sudo pip install cayenne-mqtt

I think if it could be a connectivity thing too based on the error messages. I just installed on a clean pi and it went OK, so it doesn’t look like their servers are down, though trying to browse those links on Python.org was sloooow.

It may be worth trying again in a bit later, or, if you have some other internet connection (maybe a phone to tether to, wifi, etc) to try again there to see if you have better luck.

Doing some googling on the error messages, it looks like it may be worth trying:

sudo python -m pip install --upgrade --force setuptools
sudo python -m pip install --upgrade --force pip

I should be clear that this is a 3rd party software we’re troubleshooting here, so I’m not super familiar with that error or those commands. Make backups if you have anything important on the Pi :slight_smile: The people on that project should be in a better position to offer troubleshooting with paho-mqtt.

If you’re at a dead end here, note that Cayenne-MQTT-Python can be installed without pip as well, with these commands:

git clone https://github.com/myDevicesIoT/Cayenne-MQTT-Python
cd Cayenne-MQTT-Python
python setup.py install
