Hi Gary,
What version of python do you use?.
Since 2.7.9 cert checking is enabled by default causing this kind of errors. [1]
[1] https://www.python.org/dev/peps/pep-0476/
Kind regards,
alimon
I'm using the stock python 2.7.9 from Poky/Yocto
master:901be2cb69892595443ed41ab4be285932db15eb
Is there an answer for this that's a bit less intrusive?
Perhaps there could be a DISTRO or even IMAGE feature to
enable/disable this checking?
The pep you referenced mostly talks about why this was changed
and how to disable it - manually within the python code itself.
What I don't see is where/how/what to change/import to actually
let the full certificate checking happen.

I can see that it was looking for some certificates in /usr/lib/ssl/certs
but that directory is missing.
Anyone know what I might be missing (or have misconfigured)?
Thanks
