What is the problem?

After agree to update to 1.5.0 the octoprint service does not start any more.
message on web server is :
"The OctoPrint server is currently not running"

What did you already try to solve it?

i performed some reboot, but still not working
tried manualy (as pi user):
sudo service octoprint restart without success

Have you tried running in safe mode and if so did it solve the issue?

it does not start in safe mode too (modified config.yaml to test safe mode)

Try a force-reinstall, looks like something might be corrupted. Let's hope that you haven't been pulling the power on it:
~/oprint/bin/pip install --force-reinstall --no-cache-dir octoprint

Does not work :

pi@octopi:~ $ ~/oprint/bin/pip install --force-reinstall --no-cache-dir octoprint
Traceback (most recent call last):
File "/home/pi/oprint/bin/pip", line 6, in
from pip._internal.main import main

import logging
File "/usr/lib/python2.7/logging/init.py", line 26, in
import sys, os, time, cStringIO, traceback, warnings, weakref, collections
ValueError: bad marshal data (unknown type code)

looks like there is some python issue, strange, may be some plugin install broke the python.

Sounds like corruption to me...

Yep, something is seriously corrupted in the virtual environment there. If you are in the habit of just powering off the pi without shutting it down through the system menu first, stop doing that.

This might fix it (but you will have to reinstall your plugins, your settings will persist however):

mv ~/oprint ~/oprint.broken
virtualenv ~/oprint
~/oprint/bin/pip install OctoPrint
sudo service octoprint restart
