Install a New Certificate

1. Do cd /usr/share/ca-certificates
2. Run sudo mkdir custom- create a directory called "custom"
3. Download the CA certificate of the proxy and save it into "/usr/share/ca-certificates/custom/proxy.crt"
4. Run sudo chmod 644 custom/proxy.crt
5. Run sudo apt install ca-certificates
6. Run sudo dpkg-reconfigure ca-certificates and select "All" in the prompt
7. To test that it works, do curl --proxy <your secure proxy address> https://api.intsights.com/test-connection

• This should work now. It will give you new file in /etc/ssl/certs

8. Do systemctl restart docker
