Problem restarting: haven't been able to update plugins for a while


#1

After running a "succesful" plugin upgrade (MQTT in this case but it applies to all), the servers doesn't restart and if I go back to the page, I can see it's not ben updated. Stopping the server and restarting it doesn't solve the issue

Server was started this way: OctoPrint ~/OctoPrint/venv/bin/octoprint serve

What did you already try to solve it?

I have ugpraded pip. That didn't help.

I have run this again:

source venv/bin/activate
pip install pip --upgrade
pip install https://get.octoprint.org/latest

which got me to pip: 19.0.3 and reverted to Octoprint 1.3.9 but that didn't help and I can't update to 1.3.10 anymore (same as updating a plugin).

Additional information about your setup (OctoPrint version, OctoPi version, printer, firmware, octoprint.log, serial.log or output on terminal tab, ...)

OctoPrint 1.3.10

That's probably why it doesn't work now, if I'm guessing correctly. I think it's time for a start-over.
