Just updated to 1.8, rebooted the raspberry pi, now OctoPrint won't start, that's the message I get when I try to run it via command line :
/home/pi/OctoPrint/venv/bin/octoprint serve

I tried to update the Jinja2 version with no result but I'm not even sure that's the real problem. I really need the help of someone with more experience in this kind of issues.
