Hi Stephen and Odhiambo,
My venv is located at /opt/mailman3/venv and so I used the command, "python3 -m venv --upgrade /opt/mailman/venv" to upgrade the venv which appeared to run successfully, however, afterwards the mailman3 service always exits immediately after the command "systemctl start mailman3". The mailman3-web service appears to run correctly, however, when I browse to the mailman3 web interface then I get the following error:
Something went wrong Mailman REST API not available. Please start Mailman core.
I will note that the Django Administration web interface was not working until I executed "python3 -m venv --upgrade /opt/mailman/venv" after which the Django web interface started working properly. However, as I noted, the mailman3 service is still not working since it always exits immediately after being started.
I have run out of ideas. Does anyone have any suggestions?
Thanks,
Gordon
