I ran into an issue with AWS CLI on Ubuntu 16.04. I was getting this error, “AWSHTTPSConnection’ object has no attribute ‘ssl_context” every time I try to do a simple “aws s3 ls” command. So, here’s the fix.
Assuming you installed “awscli” using apt. Go ahead and uninstall it.
apt remove awscli
Install awscli using pip instead.
apt install python-pip pip install awscli aws --version
If this is a fresh install, you may have to run “aws configure.”
