Pip install fails with "Connection broken"

I am having issues with using pip in a resin based image. My Dockerfile is the following:

FROM resin/raspberrypi3-python:3.6
MAINTAINER Andrew Kail <andrew.a.kail@gmail.com>

RUN [ "cross-build-start" ]

RUN apt-get update  
RUN pip install Django

RUN [ "cross-build-end" ]

When it hits the ‘pip install’ I get the following error.

I am building on Manjaro Linux with docker version 18.01.0-ce and kernel 4.14.16-1.

Some google searching has shown issues in Travis CI that are the same, but the fix did not work for me.

Also, I am able to do these builds without issue using x86 based images doing the exact same docker commands.

Has anyone experienced this before and worked around it? I’m at a loss.



This looks like a temporary network failure. I just pushed a project that downloads Django and it built correctly.
Could you please try again?

I agree. Everything I have found points to that being the issue. I am not currently pushing anything to resin, just starting to get started with building rpi3 images on my personal device.

Its a little strange that apt-get update (and upgrade) are working fine. Same build works fine with alpine and debian x86 images.

Next I may try another resin arm image and then do a tcpdump to see what the network traffic over the docker interface looks like.

Tcpdump with wireshark. ZeroWindow Error

157 1.798524 TCP 54 [TCP ZeroWindow] 41582 → 443 [ACK] Seq=1798 Ack=852072 Win=0 Len=0

Build fails identically with resin/armv7hf-debian image as well.
