I am running a mongo db docker container on a network using only https. The container uses apt-get for installing packages. Since network allows only https connections,apt-get is not working for me. 
I have tried to change http with https in /etc/apt/sources.list and /etc/apt/sources.list.d after installing apt-transport-https. But nothing worked for me. 
Here is my /etc/apt/sources.list after replacing https with https

 deb https://deb.debian.org/debian jessie main
 deb https://security.debian.org/debian-security jessie/updates main
 deb https://deb.debian.org/debian jessie-updates main

The mongodb-org.list file in /etc/apt/sources.list.d looks like 

 deb https://repo.mongodb.org/apt/debian jessie/mongodb-org/3.2 main

after doing all this apt-get update shows
