-- EDIT -- 3 Sept 2021

Since April of 2019, there are no longer updates for Ubuntu 14.04 which seems to have broken the installation steps that are outlined above.

Further to this, it seems that certbot-auto is no longer supported.

I have not tested any solution as no longer make use of 14.04.

This said, in 14.04 you could perhaps try to install snapd:

sudo apt update
sudo apt install snapd

Remove the existing certbot-auto install:

sudo rm -rf /usr/local/sbin/certbot-auto

Then try to use snap to install certbot:

sudo snap install --classic certbot

The steps for 16.04 would perhaps be the same with the only exception being, snap is already installed in 16.04 so you would simply need to update it:

sudo snap install core; sudo snap refresh core
    
When I had created this gist, the instructions on how to make use of Lets Encrypt were not very clear.

since then things have changed a lot and there is great documentation available for you to make use of:

You still need it?

Likely because you have linked to the assets in your cost by using http:// and not https://

Yes that was the case... funnily enough we weren’t getting warnings before the earlier certificate got expired AKHIL MATHUR​​ ​DIRECTOR TECHNOLOGY Absolut Info Systems Pvt Ltd Assotech Business Cresterra, Tower 1, 2nd Floor, Sector-135 , Noida 201301, INDIA M: 9818310336
