SSL Verification error

[ifuchs]

I am trying to install pushover-cli on a Debian (buster) docker container. When I run pushover-cli, I am getting the following error:
ssl.SSLCertVerificationError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1056)

I realize that this is not a pushover-cli problem per se, but can anyone tell me how to go about resolving this? I tried a half dozen suggestions that a search of this error found but none seemed to help.

https://docs.python.org/3/library/http.client.html
"Changed in version 3.4.3: This class now performs all the necessary certificate and hostname checks by default. To revert to the previous, unverified, behavior ssl._create_unverified_context() can be passed to the context parameter."

Change this:

conn = http.HTTPSConnection(proxyhost, int(proxyport))

to this:

conn = http.HTTPSConnection(proxyhost, int(proxyport), context = ssl._create_unverified_context())

You may need to import the ssl library
import ssl
