OpenSSL version issue

Product support balenaOS
,

I am using balena dashboard along with screenly ose, I have created a docker file to start the screenly-viewer, screenly-server, screenly-websocket and screenly-celery services. On running the docker file I’m getting the following issue:

error_log
error_log1090×449 250 KB

The versions used are:
Python == 2.7
OpenSSL == 1.0.1t
Cryptography == 2.8

Also I am getting this issue only on some devices from last 3-4 days.

Hi,

Are you using official Python base images or balena base images? If it’s balena base images, can you please share your Dockerfile with us?

5

Possibly, it is an issue with the cryptography package, how did you install that package? From OS package manager or via pip?

I have installed cryptography pacakge using pip( pip install cryptography==2.8
) in the docker file of scrrenly-ose

Can you please upgrade it via pip in your Dockerfile and try again?

The command I have used in docker to install packages is
pip install --upgrade -r /tmp/requirements.txt

Since you pinned it as cryptography==2.8 so it will force install that version and won’t install the latest one. You should change it to unpinned versions like (cryptography>=2.8) and see if it works.
