Hi I am using ubuntu 14.04.5 until it reaches end of life in April next year. In my console it says 35 security updates can be installed. But when I run sudo apt-get update -> sudo apt-get upgrade it says no packages can be updated.

I am not clear on whether my server has the latest updates.

I have taken a screenshot of my console here:

I understand it is best to upgrade to 18.0.4, but I don’t have time to do this until next year, until then I want a secure server while using 14.0.5.
