[Solved] Failed to start Indico Celery

When I run
systemctl status indico-celery
I get
indico-celery.service - Indico Celery
Loaded: loaded (/etc/systemd/system/indico-celery.service; enabled; vendor preset: enabled)
Active: failed (Result: exit-code) since Wed 2020-03-18 10:36:21 UTC; 41s ago

Failed to start Indico Celery
The celery.log is empty.

if you use different users/paths you have to adapt the /etc/systemd/system/indico-celery.service file and reload systemd afterwards.

Yes, I used a different venv path. Thankyou.
