Polar Cloud Failed to Install

Plugins
1

Hello everyone,

I'm trying to install the Polar Cloud plugin that was mentioned on a recent blog of Gina's. It is failing for me :frowning: Any assistance would be greatly appreciated. In the log it mentions having an older version of pip, so I tried upgrading that and that failed too.... btw, I just tried installing the plugin using OctoPrint's plugin manager. Here is my setup information below, then the log error.

OctoPrint Version 1.3.9
OctoPi Version 0.13.0

According to that error, I think it's suggesting that you cough up the indicated log file for us to review.

That's weird... I cut-n-pasted that log also... Here it is:

That looks pertinent.

And this one also seems to include the same line at the bottom about splitlines.

Taking that error to Google, turns up this issue on the Polar Cloud repository.

The author indicates that this should no longer be a problem. Some in the thread indicated that by manually removing the current version of OpenSSL (which came with the OctoPi image) the Polar Cloud install worked:

I manually removed the OpenSSL folder with:

rm -rf ~/oprint/lib/python2.7/site-packages/OpenSSL

and then it worked.

It's up to you whether you'd like to try this. It may be worthwhile checking in with that thread and letting the author know that it's failing for you.

This is great information! Thanks I will
