No web interface after 1.8.3 upgrade

What is the problem?

After upgrading to OctoPrint 1.8.3, my web interface is gone. I have a message saying "The OctoPrint server is currently not running"
It recommends refreshing...

  • waited 5 minutes +, same.
    It says to verify the process is running. I get no results from the command, which indicates (to me) it is not running (command to run is ps -ef | grep -i octoprint | grep -i python.) It just goes to next line.

What did you already try to solve it?

I have fully powered off Pi, and printer, multiple times. Same result.
I have reviewed the log, and found that it complains about a plugin, but is starting in safemode. It then has some unhandled exception.

Have you tried running in safe mode?

According to the log, it is starting in save mode due to failed starts, and then having an unhandled exception.

Did running in safe mode solve the problem?


Systeminfo Bundle

pi@octopi:~ $ octoprint systeminfo
-bash: octoprint: command not found

I'm not able to get to the web interface. SSH only. Octoprint not able to run, so not able to export system info. Let me know what files or other info you'd like. I will attach the log.

Additional information about your setup

OctoPrint version, OctoPi version, printer, firmware, browser, operating system, ... as much data as possible
Printer is SOVOL SV01 connected via USB.
Running OctoPi 0.17.0

Everything has been working great for some time. When I check python version, i'm getting ...
python --version = 2.7.16. python3 --version = 3.7.3

My Pi / Print versions via ssh...

pi@octopi:~ $ ~/oprint/bin/octoprint --version
octoprint, version 1.8.3

pi@octopi:~ $ cat /etc/octopi_version
octoprint.log (13.2 KB)

Please help. :slight_smile: FYI - I am a Patreon supporter.

Worst case, is there a guide or info on how/what to get off of this thing, before I reimage and start clean?

Can we see the error in the log please? That's the only way that anyone will know what the problem is. We're not mind readers.

There's a couple of already known common problems people have installing 1.8.3+, most of which we've already figured out a solution for - if you have a log it would confirm the problem.

Message that shows in the browser....

The OctoPrint server is currently not running

If you just started up your Raspberry Pi, please wait a couple of seconds, then try to refresh this page.

If the issue persists, please log into your Raspberry Pi via SSH and check the following:

  • Verify that the process is running: ps -ef | grep -i octoprint | grep -i python should show a python process:

pi@octopi:~ $ ps -ef | grep -i octoprint | grep -i python
pi 1441 1 6 11:12 ? 00:00:15 /home/pi/oprint/bin/python
/home/pi/oprint/bin/octoprint --host= --port=5000

  • If it isn't, the question is why. Take a look into ~/.octoprint/logs/octoprint.log, there might be an error logged in there that helps to determine what's wrong.
  • You might also want to try if you can restart the server (if no obvious error is visible): sudo service octoprint restart.

If all that doesn't help to trouble shoot the issue, you can seek support on the OctoPrint Community Forum. Please provide your OctoPi and OctoPrint versions as well as your octoprint.log and explain what you already tried and observed as detailed as possible.

I do apologize - I read your post twice and didn't see the log file for some reason. I'll blame it on a lack of sleep recently I think....

Anyway, the error that is there is one that has been seen before - please check my post linked below for details of how to fix the issue. So far we think it's likely to be a pip bug, only affecting those with pip 20.2 for some reason.

No problem. Totally get the lack of sleep bit.

I've tried this, and I get "pip: command not found". I'm typing in (same result with or without sudo)
pip install -U pip

Try using "pip3 install -U pip" then "pip3 install typing-extensions==4.3.0"

The command pip should be linked to pip3 but for some systems it may not be.

First you will need to activate the virtual environment where OctoPrint is installed - in OctoPi (& your install) this would be running source ~/oprint/bin/activate` first, and then running those commands should work OK.

AND... We are BACK! Thank you Charlie!!!
