Plugin installation fail

What is the problem?
Installing plugins from webUI fail every time

What did you already try to solve it?
Downgraded pip to 9.0.3 according to
Restarted server
Used various combinations of addresses and ports (5000, 80)

Additional information about your setup (OctoPrint version, OctoPi version, printer, firmware, octoprint.log, serial.log or output on terminal tab, ...)
Latest raspbian PC version, 1.3.8 OctoPrint, Pip 9.0.3 (after downgrade from 10.0.1)
Interestingly enough, running command like this via SSH works:

/home/pi/OctoPrint/venv/bin/python2 -m pip install

This line was taken from plugin manager console log.

I have uploaded logs and a webUI error message (49.0 KB)

Me too, same issue with webui plugins, but dos cmd works.


Some more reading and upgrade to OctoPrint 1.3.9rc1 solved the problem.

Known issue.

will wait for stable version.


Interestingly, as this is my second install, I have this problem now as I installed 1.3.8 directly. Before, I had 1.3.7 upgraded to 1.3.8 on Ubuntu and did not have this issue.
