Describe the bug I tried installing VOLTTRON but no success. I had installed and used it for a year and it was working fine. Recently, I deleted the VOLTTRON folder and decided to do the installation afresh again. I am surprised to see no success to this time. Don't know why?

To Reproduce

Steps to reproduce the behavior:
sudo apt-get update 
sudo apt-get full-upgrade 
sudo apt-get install build-essential python3-dev python3-venv openssl libssl-dev libevent-dev git
sudo apt-get install libffi-dev
git clone https://github.com/VOLTTRON/volttron
cd volttron
python3 bootstrap.py 
source env/bin/activate
./start-volttron

Did you remove your VOLTTRON_HOME (~/.volttron) when upgrading?

Check the ~/.volttron/config file, it should have [volttron] at the top of the file.

I am sure I did not remove any VOLTTRON_HOME when upgrading. Can you please let me know how to do it. In the process of debugging the error, I manually deleted the /home/pi/volttron folder and performed the VOLTTRON installation as per the list of codes given below. This I have done over a dozen times hoping to fix the error. Looks like my following installation instructions do have incomplete steps. Can you please guide me to a list of codes I can execute to install the VOLTTRON successfully. It is hard to find on the VOLTTRON documentation website.

I checked ~/.volttron/config file. It does have following:


pi@raspberrypi:~ $ cat ~/.volttron/config
[volttron]
message-bus = zmq
vip-address = tcp://127.0.0.1:22916
instance-name = tcp://127.0.0.1:22916
pi@raspberrypi:~ $


**COMPLETE VOLTTRON INSTALLATION STEPS:** 
Step1: Install prerequisites. Execute the following one by one.

sudo apt-get update sudo apt-get full-upgrade sudo apt-get install build-essential python3-dev python3-venv openssl libssl-dev libevent-dev git sudo apt-get install libffi-dev

Step2: Clone VOLTTRON code. The voltron will download into the home directory.

`git clone https://github.com/VOLTTRON/volttron --branch main`

Step3: Set up virtual environment. Just go for ZMQ bus installation and this is easier and faster to install. I did not install RabbitMQ.

cd volttron python3 bootstrap.py # Coffee is a good to have now. It takes good time. source env/bin/activate # activate the volttron platform

Step4: Test the VOLLTRON.

start the volttron

./start-volttron

vctl stands for volttron control; install an agent (listens to user and controls something) by giving a tag name

vctl install examples/ListenerAgent --tag listener

now make the agent start/run

vctl start --tag listener

check the status of listeners

vctl status

check the volttron log files

tail -f volttron.log

to stop the volttron

./stop-volttron

to deactivate the volttron platform

deactivate
