apt-get upgrade breaks python3 - edwinbmiller - 03-30-2018

was using rock64 for python3 development, but after running 
apt-get update
apt-get upgrade

notice that running python3 just gives me segmentation fault

anyone had this experience on debian stretcg python3.5?

RE: apt-get upgrade breaks python3 - edwinbmiller - 03-30-2018

reinstalled debian stretch 4.4.77 and did a
apt-get update -y
apt-get install linux-rock64 -y (instead of pt-get upgrade)

then ran the following python

switched over to xenial and no longer have problems with python3

more good news was able to install pip & upgrade it successfully on xenial minimal with kernel 4.4.77

apt-get install python3-pip
pip3 install --upgrade pip

What did you use before? Bionic? Bionic is still not released and in beta, so if you find issues there, report them to the Ubuntu upstream bugtracker...

debian stretch Wink  So I'm guessing it was an 'old' bug in a python C library that has since been resolved...

RE: apt-get upgrade breaks python3 - edwinbmiller - 04-01-2018

also did try this with python3

https://github.com/ayufan-rock64/linux-build/releases/download/0.6.29/xenial-containers-rock64-0.6.29-201-arm64.img.xz

but is this release of xenial is broken in regard to python3, so went back to 0.5.15: jenkins-linux-build-rock-64-136 which seems to work fine.
also did try artful but had lots of issues.

RE: apt-get upgrade breaks python3 - edwinbmiller - 04-01-2018

just tried bionic prebuild with perl and python3 and works fine

https://github.com/ayufan-rock64/linux-build/releases/download/0.6.30/bionic-minimal-rock64-0.6.30-208-armhf.img.xz

so the 2 builds i've had the best luck with for python3 are:

release xenial-minimal-rock64-0.5.15-136-armhf.img.xz
prerelease bionic-minimal-rock64-0.6.30-208-armhf.img.xz

debian stetch in general seems broken with python3?

RE: apt-get upgrade breaks python3 - prof7bit - 04-02-2018

same problem here.

Is there any way to fix it?

RE: apt-get upgrade breaks python3 - prof7bit - 04-02-2018

downgrading the kernel to 

  linux-image-4.4.77-rockchip-ayufan-136

seems to make the problem disappear. Also with 4.4.114-rockchip-ayufan-193 it seems to have worked, that was the version I have been using for a few months now, only today when I upgraded from -193 to -208 it broke. So it must somehow be related to something that changed in the kernel.

It also segfaulted not always immediately and not deterministically, in 2 out of 5 attempts it was possible to start a python shell without segfault before the prompt but trying to run a script was still impossible.

RE: apt-get upgrade breaks python3 - bony - 04-26-2018

I use latest pre-release img,
stretch-minimal-rock64-0.6.32-210-arm64.img.xz
Segmentation fault also come up with high probability.
I'm not sure if this issue is only show in arm64 while works fine in armhf.
