Plugins timing out during install


#1

Hi,

I have octoprint installed on a raspberry pi B +. I have been using it for a few weeks with no problems and have installed a couple plugins like the bed visualizer. Today when I went to install Octolapse I keep getting errors. Has anyone seen this before?plugin_pluginmanager_console (2).log (72.2 KB)


#2

Feels like a Python v2.x versus v3.x sort of thing.

Thanks for the reply. Is there anything I can check? Here is what I see during the startup

I'd thought that foosel was going to ramp up Python on the 1.3.9x image but I'm probably confused. My 1.3.9rc4 is also using python2.7 like you are.

If I do the following, it now reports v10.0.1 of pip in the virtual environment (which she rev'd up recently).

cd ~/OctoPrint
source venv/bin/activate
pip --version
pip 10.0.1 from /usr/local/lib/python2.7/dist-packages/pip (python 2.7)
deactivate

It would be interesting to see if you have the same version of pip.

I downgraded mine from 18.0

/home/pi/oprint/bin/python2 -m pip --version
pip 9.0.3 from /home/pi/oprint/local/lib/python2.7/site-packages (python 2.7)

You are using pip version 9.0.3, however version 10.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

@foosel is the best person to advise on this. I'm sure the dependency stack needs to be just right on this.


#8

That looks like your OctoPrint instance can't fetch required dependencies from pypi - see that "Read timed out" message there regarding pyhonhosted.org. Could be something as simple as a hiccup on their side, or something being off in your network. Same error throughout your uploaded log.

Note that this isn't an OctoPrint issue, it's an issue a couple layers down - pip is a stock Python utility that OctoPrint only uses for installing plugins & updates, it is required to work properly and here it looks like there are some issues. I just did a quick test and for me Pillow downloads just fine off PyPi, so either it was a temporary issue (status.python.org doesn't show any incidents though) or it's something off in your local network.


#9

I suppose it could be a DNS problem as well...


#10

For a DNS issue I'd expect an "unknown host" error though, not a read timeout.


#11

In my case, it would be the guys who are jack-hammering the street outside for the last few weeks, installing new Internet cabling. <_<
