vbatts/slackware docker image can't connect to https

So I've been playing with a docker image from vbatts
mentioned here:
https://docs.slackware.com/howtos:mi...e_docker_image

But I seem to have issues connecting to https urls.

example:
Code:sh-5.0# wget https://github.com/sbopkg/sbopkg/releases/download/0.38.1/sbopkg-0.38.1-noarch-1_wsr.tgz
--2021-03-07 04:35:00-- https://github.com/sbopkg/sbopkg/releases/download/0.38.1/sbopkg-0.38.1-noarch-1_wsr.tgz
Resolving github.com (github.com)... 140.82.113.3
Connecting to github.com (github.com)|140.82.113.3|:443... connected.
ERROR: cannot verify github.com's certificate, issued by 'CN=DigiCert SHA2 High Assurance Server CA,OU=www.digicert.com,O=DigiCert Inc,C=US':

To connect to github.com insecurely, use `--no-check-certificate'.
'.
I've added :
Code: slackpkg -batch=on -default_answer=y install ca-certificates
slackpkg -batch=on -default_answer=y install openssl-solibsis there some other packages I should add to support https (ssl) webpages via wget

((use `--no-check-certificate'. does work but would like to not be doing this))
