Group=www-data 
WorkingDirectory=/root/revamp 
ExecStart=gunicorn --access-logfile - --workers 3 --bind unix:/root/revamp/revamp.sock revamp.wsgi:application

Son vous dire qu'il ne veut pas un chemin relatif pour l'exécutable gunicorn:
Executable path is not absolute, ignoring.

Vous devez changer le chemin absolu de votre exécutable gunicorn, soit:

• exécutable du système: ExecStart=/usr/local/bin/gunicorn
• votre exécutable environnement virtuel: ExecStart=/path/to/venv/bin/gunicorn

Vous pouvez vérifier ce point essentiel : Using Systemd to Make Sure Gunicorn Starts on Boot, pour un fichier de configuration de service système gunicorn minimal.

Espérons que cela aide!
