SSL: CERTIFICATE_VERIFY_FAILED

[drount]

Hello,

after building an image yesterday based on:
FROM tiangolo/uwsgi-nginx-flask:python3.8 or
FROM tiangolo/uwsgi-nginx-flask:python3.7

I got this error when conecting to any HTTPS server:

ERROR: Unable to download webpage: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1076)> (caused by URLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1076)')))"

I had to add:
RUN apt-get update && apt-get install -y ca-certificates
to my Dockerfile in order to fix it.

Reporting just in case you want to add it to the root image or it helps anybody in the future.

Hey, @drount ! Thanks for giving the fix 💙 . I was facing the exact same problem and this helped a lot.

Looking at the dates, it seems docker hub should be updated with that fix, but I still have server certificate verification failed. when pulling git requirements for example.

[drount]

I don't see the changes in the source code

Had to add this to my own docker file and this seemed to fix it for me:

RUN apt-get update
RUN apt-get install -y --reinstall ca-certificates

[gamarobert]

i believe this is still an issue. above suggestions didnt work for me

How can I fix this on windows?

This is still an issue for me too. Had to run ca-certificates as described to fix
